stdenv: introduce baseHash() to replace stripHash()

stripHash uses a global variable to communicate it's computation
results, but it's not necessary. You can just pipe to stdout in a
subshell. A function mostly behaves like just another command.

baseHash() also introduces a suffix-stripping capability since it's
something the users of the function tend to use.
