configure: silence 'shift' error message in version_ge()
If there are less than 2 arguments in version_ge(), the second
'shift' prints this error:
../configure: line 232: shift: shift count out of range
As Eric suggested, we can use 'shift ${2:+2}' which works out to
'shift 2' if $2 is set, or 'shift' (implicitly shift 1) if $2
is not set.
This patch replaces both 'shift; shift' occurrences in version_ge()
with 'shift ${2:+2}'.
