gio/meson: Make possible for test to depend on extra programs

We have some test programs on which some tests depend on, for example
appinfo-test is a tool that is used by the desktop-app-info tests.

So test can now have an 'extra_programs' key where the extra program
names can be included.

This could have been handled manually via 'depends', but this allows
to avoid repeating code and be sure that all is defined when extra
programs targets are checked.
