missing include in mksignames.c

[Jean Laurent]

When trying to build bash 2.05 (release) on ibm ppc aix, 
compilation failed during execution of mksignames.

After some examinations, it appears that mksignames.c
doesn't include config.h.

On AIX, SIGRTMAX is defined as 999, and must be undefined 
by UNUSABLE_RT_SIGNALS (which is set in the 
unincluded config.h).

After adding the missing include, the build succeded.


./bash --version
