[PATCH] fix quotearg when wchar.h is not used

[Paolo Bonzini]

While testing GNU sed's bootstrap mode (where it handcrafts a minimal
config.h to work around system without a sed, or whose sed is not 
powerful enough to run configure), I found a bug in quotearg.c.

If HAVE_WCHAR_H and HAVE_MBRTOWC are not set, various functions are
#defined to work only on single-byte locales, but a mbstate_t variable
is defined around line 420.  Fixed with the attached trivial patch.
