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.
