In the interest of code hygiene, make it easier to compile Git with the
flag -pedantic.
Pure pedantic compilation with GCC 7.3 results in one warning per use of
the translation macro `N_`:
warning: array initialized from parenthesized string constant [-Wpedantic]
Therefore also disable the parenthesising of i18n strings with
-DUSE_PARENS_AROUND_GETTEXT_N=no.

Now with -DUSE_PARENS_AROUND_GETTEXT_N=0 instead of =No.
This is the convenience knob for all developers that led to the series
bb/pedantic[1]. It does not depend on this series, though.
