ci: Fix OPTS not being passed to OSX builds.

Before GHA, OPTS were always passed as an argument for a *-build.sh
script.  But that changed.  Linux builds are using the OPTS variable
from the environment, but OSX script does not, so the options are
currently ignored.

That wasn't a big issue until now, because SSL was not available or
the build actually worked on newer branches.  But GHA recently updated
OpenSSL to 3.0+ and we have deprecation warnings on branches that do
not support OpenSSL 3.0+ (branch 2.16) and that breaks the build.

Fixes: 6cb2f5a ("github: Add GitHub Actions workflow.")
