Improve speed of compiler launcher command in UseCcache.cmake

I noticed that the overhead of “cmake -E env” is around 9 ms on my
system. This means that ccache direct mode hits on average have become
twice as slow when building ccache itself on my system.

Improve this by using the standard “env” program if available. Its
overhead is around 1 ms.
