Fix regexp compiler with translation table

[Andreas Schwab]

build_wcs_buffer didn't set mbs when a translation table is used.  This
can result in all kinds of random behaviour during parsing due to use of
uninitialized memory.

	* posix/regex_internal.c (build_wcs_buffer): Also set pstr->mbs
	when translating.
