libtomcrypt: fix build without wchar

GCC defines wchar_t even when wchar support is disabled in uClibc. The
LTC_NO_WCHAR macro triggers a local definition of wchar_t that conflicts
with the GCC defined one. Remove LTC_NO_WCHAR to avoid that.

See also https://github.com/libtom/libtomcrypt/issues/313 for more
discussion about this.
