Change alternate space base name from /emul/ibcs2 to /compat/ibcs2,

Browse Source 
in line with linux alt space of /compat/linux.
This was pointed out by Stefan Esser.

In cheching alt space for libraries in imgact_coff.c, use const
ibcs2_emul_path instead of its own local string.  Also do a proper
malloc of temp name according to MAXPATHLEN.
