[PATCH] strptime: avoid compiler warnings

[Eric Blake]

Reported against mingw, but reproduced on glibc with:

CFLAGS='-Wall -Wunused-label -Wunused-variable' \
  ac_cv_func_strptime=no ./gnulib-tool --with-tests --test strptime

* lib/strptime.c (__strptime_internal) [!_NL_CURRENT]: Avoid
compiler warnings about dead code.
Reported by Daniel P. Berrange.

Easy enough to fix.
