systemtap: remove explicit msgfmt check

Passing --disable-nls should be enough to disable the requirement for a full
gettext to be present, but the upstream configure explicitly checks for msgfmt
even if it isn't going to be used.  To avoid having to depend on gettext-native,
patch this check out.
