fix "osci.brew-build.rpminspect.static-analysis" gating test

Perl's ExtUtils::Install installs "Guestfs.so" read-only; that prevents
objcopy from adding the ".gdb_index" section for the sake of the debuginfo
file. See <https://rt.cpan.org/Public/Bug/Display.html?id=40976>. Lack of
".gdb_index" is then flagged as an error by rpminspect. Restore write
permission for the user, on "Guestfs.so".

(This has nothing to do with RHBZ 2209279 BTW, but the bots don't let us
commit maintenance-only patches.)
