src/modules/bootloader/main.py (install_secureboot): Run the configured
grubMkconfig command (should be `grub-mkconfig` or `grub2-mkconfig`) to
create `/boot/efi/EFI/$efi_bootloader_id/grub.cfg`. The sb-shim is just
a chainloader to GRUB 2, which expects a grub.cfg in that location, so
something has to create it or the installed system will not boot beyond
the GRUB rescue shell.
(install_grub): Fix misleading comment above the grubMkconfig call: it
is not the file specified in grubCfg that should be already filled out
by the grubcfg job module, that file is written by `grub*-mkconfig`
using `/etc/default/grub` as the input file. It is that input file
`/etc/default/grub` that should already be filled out by the grubcfg job
module. (The same input file is used in install_secureboot.)
- The output of subprocess is a bytes object, which needs to
be decoded so we can use it like a regular string (alternatively,
we could have changed more code to manipulate bytes, but eventually
we need a string to pass to a subsequent command anyway).
- Centralize the sanitizer so that it's consistent in different
environments.
- While here, add () to the sanitizer to avoid some distro's with
parenthesized names from creating weird EFI dirs.
When choosing `systemd-boot` as the bootloader, numerous problems
occurred:
- the kernel and initrd were not copied to the EFI System Partition,
and therefore could not be reached by the bootloader
- the fallback entry used the default initramfs image instead of the
fallback image
`systemd-boot` provides the `kernel-install` utility, which
automatically copies the kernel + initramfs to the EFI partition, and
creates the corresponding bootloader entry.
Unfortunately, `kernel-install` cannot be used here as the module is not
executed in a chroot. As setting up one only for running a single
command would be overkill, this patch re-creates what `kernel-install`
usually does:
- copy the kernel and initramfs to their own subdirectory at the root of
the EFI partition
- create the corresponding entry configuration file
To this end, the `systemd-boot` installation code in the `bootloader`
module has been largely refactored, including removing a few duplicate
LOCs.

- to make it short - it doesn't help much if one try to find and process any
EFI related things in the live system. The better approach is to search in
the chroot.
- use python builtins for mkdir and cp
- replacing some subprocess calls
- Some PEP8 changes
- added myself to the copyright section
