Lennart Poettering 78f81f02e8 boot: skip random seed handling if seed file is marked read-only
If the read-only FAT file attribute is set on /loader/random-seed,
don't update the seed file — and hence don't use it either, since a
seed we cannot update would be the same on every boot.

This gives users an explicit way to turn off random seed handling by
marking the file read-only, useful for example in pre-built OS images
that are replicated to many systems, where the baked-in seed is shared
and hence must not be credited.

The check is done upfront in process_random_seed(), before any other
work, mirroring the existing check for read-only volumes. This covers
both systemd-boot and systemd-stub, which share this code.
