Instead of unconditionally requiring modules such as File::Spec, let's
only load them when needed. This speeds up code that only needs a
subset of the features Git.pm provides.
This brings a plain invocation of "git send-email" down from 52/37
loaded modules under NO_GETTEXT=[|Y] to 39/18, and it now takes
~60-~70ms instead of ~80-~90ms. The runtime of t9001-send-email.sh
test is down to ~13s from ~15s.
