gpt-auto-generator: do not fail on missing libcryptsetup when verity

is not used

add_veritysetup() is called unconditionally  from add_root_mount() and
add_usr_mount() whenever in_initrd() is true, to generate units that
only activate if verity devices appear. However, when compiled without
libcryptsetup, this function returned a hard error, causing the entire
generator to fail even when no verity protection is in use.

Change the #else fallback to log a debug message and return 0, matching
the pattern already used by add_root_cryptsetup().
