When using the `rawfs` module for copying data, it may be useful to
save the source device used for later checks or actions. This commit
therefore adds a `source` field to each corresponding partition entry in
global storage, so that this information can be retrieved later during
the installation process.
Another small improvement is that global storage is now modified only
once (it was previously modified as many times as there were entries
processed by the `rawfs` module).

In its current state, the 'rawfs' module requires the source partition
to be identified either by its mount point or device name, but using a
symlink to either one (e.g '/dev/disk/by-uuid/...') would fail.
This patch fetches the real path of source partition, allowing the use
of symlinks.

In some cases, we might want to copy a filesystem as if we were using a
simple 'dd' command, in order to create an exact copy, down to the block
level.
This can be useful in particular when working with dm-verity for
checking the rootfs integrity: that way, we can make a direct copy of
the rootfs and its verity partition and keep the system usable.
This patch adds a new 'rawfs' module to calamares, making possible to
block-copy a filesystem to a block device.
