Use ghc-paths in c2hs executable to support cross-compiling where ghc's executable name is prefixed, for eg. x86_64-unknown-linux-musl-ghc.

Otherwise this error is raised:

c2hs: does not exist (file: `Uncaught fatal error: ghc: readCreateProcessWithExitCode: posix_spawnp: does not exist (No such file or directory)
