bitbake.conf: change ccache path to use MULTIMACH_HOST_SYS

Currently if I build packages for several targets (e.g. for armv5te tosa
and for armv7a beagleboard) oe will use single ccache dir for both of
those targets: build/ccache/arm-oe-linux-gnueabi. However those targets
use different opcodes, different features and binaries created for one
of those targets wont't run on the lower one. So use MULTIMACH_HOST_SYS
for ccache dir, so that it uses something like
build/ccache/armv5te-oe-linux-gnueabi dir.
