ci: make Perforce binaries executable for all users

The Perforce binaries are only made executable for the current user. On
GitLab CI though we execute tests as a different user than "root", and
thus these binaries may not be executable by that test user at all. This
has gone unnoticed so far because those binaries are optional -- in case
they don't exist we simply skip over tests requiring them.

Fix the setup so that we set the executable bits for all users.
