[xml] xmlModulePlatformSymbol() doesn't work on HP-UX

[Albert Chin <libxml mlists thewrittenword com>]

HP-UX uses shl_load() and, if the correct patch is installed,
dlopen(). xmlModulePlatformSymbol doesn't work because shl_findsym
wants a pointer to the handle. Patch below.

BTW, why the "errno = 0"? AFAIK, It's not needed.

Tested on HP-UX 10.20, 11.00, 11.11.
