gmacros: Mark G_UNAVAILABLE() functions as deprecated (gcc <= 4.4)

RHEL6 ships with GCC 4.4 by default, which doesn't understand the
nicer deprecated attribute that takes a message.  However, we can at
least fall back to the old G_DEPRECATED, rather than silently doing
nothing.

This gives me warning messages when building OSTree on RHEL6 when I
accidentally added a usage of g_unix_fd_source_new().
