Make `distutils.version.StrictVersion` available as a helper to
gyp expressions so they can do proper version checks and update
the gyp files accordingly.
Caveat emptor: `StrictVersion` does *not* like empty strings so
this commit adds truthiness guards. The helper could deal with
those but I felt it better to make it explicit.
