[COMMITTED] strip: Use ELF_CHF_FORCE to recompress any sections that were uncompressed.

- Subject: [COMMITTED] strip: Use ELF_CHF_FORCE to recompress any sections that were uncompressed.
Older gcc might create small .debug_pubtype. If such a section is compressed
then strip should use ELF_CHF_FORCE to return it to compressed state after it
is done with the section. Found by the run-strip-reloc.sh testcase on rhel6.
