kselftest/arm64: mte: Use cross-compiler if specified

Browse Source 
At the moment we either need to provide CC explicitly, or use a native
machine to get the ARM64 MTE selftest compiled.

It seems useful to use the same (cross-)compiler as we use for the
kernel, so copy the recipe we use in the pauth selftest.
