apply: replace NO_ACCURATE_DIFF with --inaccurate-eof runtime flag.
It does not make much sense to build git whose behaviour is
different depending on the brokenness of diff implementation of
the platform because the brokenness of the patch that is applied
with the tool depends on brokenness of the diff the person who
generates the patch uses. So we do not use NO_ACCURATE_DIFF
anymore, but help people to apply patches that do not record
incomplete lines correctly with a runtime flag.
