lib/util: Use charset_compat.h if SAMBA_UTIL_CORE_ONLY
When doing a CTDB standalone build we don't want to use dynconfig,
since this introduces a lot of unwanted complexity. To avoid this,
either:
* charset needs to be nobbled to avoid loading the case tables, since
this depends on dynconfig; or
* charset needs to be avoid completely, so some functions need to be
replaced with their ASCII counterparts.
The 2nd options seems more honest and less error-prone.
