git-compat-util.h: GCC deprecated message arg only in GCC 4.5+
https://gcc.gnu.org/gcc-4.5/changes.html says
The deprecated attribute now takes an optional string argument, for
example, __attribute__((deprecated("text string"))), that will be
printed together with the deprecation warning.
While GCC 4.5 is already 12 years old, git checks for even older
versions in places. Let's not needlessly break older compilers when
a small and simple fix is readily available.
