pimsync: 0.1.0 -> 0.2.0 (#380387)

pimsync now tries to create a version string using git-describe[1], but
only if there isn't an environment variable PIMSYNC_VERSION. That is
then used instead.
Also, makeFlags in fact don't change the behavior of buildRustPackage as
far as I know.
Up until now man pages were neither generated nor installed.
