Thomas Watson ddc5d34f61 nixos/tests/systemd-boot: only patch systemd-boot during update test
The update test patches the systemd-boot binary to report a known
version then tests that this is the version updated from. The previous
patch would also search the kernel and initrd binaries, which would
cause sed to write out a temporary file that might cause the disk
to run out of space and the test to fail.

Only attempt to patch binaries which contain systemd-boot (usually
`BOOT<arch>.EFI` and `systemd-boot<arch>.efi` to avoid this problem.
As a bonus, this reduces test time by 20-30%.
