osx: delay version computation on macOS builds

Before this patch, HGVER would be evaluated at the beginning of the make
execution, and would be unset because build/mercurial/ doesn't exist yet
at that point. Now we compute the version after the `make install` run
has completed.

This is backported to stable from 8626b44516c1, but that revision had an
error in the shell invocation syntax.

    return 'bob'

    return 5000

# mock the date and user apis so the output is always the same
def uisetup(ui):
    util.getuser = getuser
    util.getpid = getpid
