[PATCH 1/2] elfcompress: fix exit status in case of "Nothing to do"

[Dmitry V. Levin]

When elfcompress decides that no section data needs to be updated and
therefore the file does not have to be rewritten, it still has to exit
with a zero status indicating success.

Resolves: https://sourceware.org/bugzilla/show_bug.cgi?id=27856
Fixes: ed62996defc6 ("elfcompress: Don't rewrite file if no section data needs to be updated.")
