configure.ac: Explicitly depend on gio-unix-2.0, gio-2.0
This fixes the following on NixOS:
main_window.c:35:10: fatal error: gio/gdesktopappinfo.h: No such file or directory
35 | #include <gio/gdesktopappinfo.h>
| ^~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
The reason here is the same as xfce/xfce4-session!51 (merged),
Here references of GIO_UNIX_CFLAGS
already exists but it is never set before this commit.
Also drop references of GTHREAD_CFLAGS
since grep -inr -E 'gthread'
does not show how this is used
Also explicitly depend on gio-2.0 !41 (comment 86296)
