Do a better fake for uname information returned in utssys() call.

Browse Source 
Currently, the emulator defaults to returning "FreeBSD" as the system
name, release "3.2", and version "2.0".  Some programs want to make
sure they are on a SYSV 3.2 system and check for 3.X release number.

Use the following defines to override the defaults:
	IBCS2_UNAME_SYSNAME
	IBCS2_UNAME_RELEASE
	IBCS2_UNAME_VERSION
(should be string)
for system name, release, and version, respectively.  This allows
someone to compile the emulator into the kernel so it can pretend
to be a specific system if needed.
