postscript: Add verbatims object for not elf files

For files in PROGS or WITHSLIBS, it copies with dependent
libraries for elf file, but for non elf file, finding dependency
causes mic warning logs. Add verbatims object for non elf files
as like initrd-recovery.

This removes below mic warning messages:
   INFO  - /etc/blkid.conf: error while loading shared libraries: /etc/blkid.conf: invalid ELF header
   INFO  - /usr/bin/verityctl: error while loading shared libraries: /usr/bin/verityctl: invalid ELF header
