installkernel POSTFIX directive

[Stefan Johannesdal]

These patches add a POSTFIX directive to installkernel. Like this:

make installkernel KERNCONF=MYSMPCONF POSTFIX=.smp

The kernel would end up as "/boot/kernel.smp" and the modules as 
"/boot/modules.smp".

I also had a go at the hard coded adding of "/boot" that I felt was a 
bit illogical since it got added even if one defined DESTDIR. Things 
would end up in DESTDIR/boot while I felt that if you define DESTDIR 
then you want kernel/modules to end up in DESTDIR.

Affected files:
share/mk/bsd.own.mk
sys/conf/kern.post.mk
sys/conf/kern.pre.mk
