gnome: initialize CFLAGS environment variable to linker arguments

The CFLAGS environment variable is used for g-ir-scanner's linking pass,
It is emptied since commit 237513dff ("modules/gnome, modules/Python:
Allow injecting RPATH flags through LDFLAGS if needed", 2025-04-09);
which could even be considered a bugfix if it didn't break Fedora
quite badly.

I could not write a testcase, but the culprit seems to be the
-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 that Fedora places
in CFLAGS.  The file contains

    *cc1_options:
    + %{!r:%{!fpie:%{!fPIE:%{!fpic:%{!fPIC:%{!fno-pic:-fPIE}}}}}}

and the lack of -fPIE option upsets the linker.  Fix by priming
the contents of the CFLAGS variable with the c_link_args being used
for the build.

Fixes: #14631
