[OE-core] [[Patch v2]] Always use locale.h in grep

[Alex DAMIAN]

From: Alexandru DAMIAN <alexandru.damian at intel.com>

The changes in the grep 2.5 configuration always leave out
HAVE_LOCALE_H - it has been removed from other files, but
not from everywhere.

This leads to a crash in certain configurations where the
size of int is not the size of pointer due to using
setlocale() while being undeclared.
