Use explicit path for libtool rather than implicit invocation of xcrun.

libtool is part of the default path at /usr/bin/libtool. That binary is just a
shim that calls out to xcrun to find the actual libtool. If we're using hermetic
xcode, then we can explicitly specify the path to avoid invoking xcrun.
