qemu_capabilities: Resolve Coverity RESOURCE_LEAK 

Coverity determined that on error path that 'mach' wouldn't be free'd
Since virCapabilitiesFreeGuestMachine() isn't globally available, we'll
insert first and then if the VIR_STRDUP's fail they it will eventually
cause the 'mach' to be freed in the error path
