libical: Do not set CC explicitly for gir compiler

This ensures that right sysroot is used during build, otherwise we see
warnings in build about using wrong sysroot and it fails explicitly with
clang

x86_64-yoe-linux-ld: warning: library search path "/usr/lib/gcc/x86_6
4-pc-linux-gnu/11.2.0/../../../../lib64" is unsafe for cross-compilation

x86_64-yoe-linux-ld: cannot find /usr/lib/clang/14.0.0/lib/linux/libc
lang_rt.builtins-x86_64.a: No such file or directory

+Subject: [PATCH] cmake: Do not export CC into gir compiler
+
+this helps cross compilers where full compiler commandline defines the
+compiler rather than just CC variable, therefore let it use the default
+values from environment and not synthesize it from CMAKE_C_COMPILER just
+for this case.
