[patch] turn on config_smt in defconfig

Now that the scheduler domain degeneration patch from
Suresh Siddha was merged in the main line kernel for a
while, it is safe to turn on CONFIG_SMT broadly.  It has
zero run time cost on system that doesn't have SMT because
the SD degenerator will collapse needless domains.
