{bintools,cc}-wrapper: set up Darwin SDK paths

Browse Source 
Some compilers may know to check these paths when `SDKROOT` is set, but
it’s not assumed they do. `SDKROOT` is instead derived from the
`DEVELOPER_DIR`, and `NIX_CFLAGS_COMPILE` is set up with the sysroot and
necessary framework and include search paths.
