sstate/bitbake.conf: Use pigz if available
Currently the compression of sstate objects is single threaded. In the case
of ltp, this takes around 33s. If we add pigz into the list of non-fatal
HOSTTOOLS and then use if it available when building the sstate object,
this time drops to around 6s.
Since pigz is now widely available this is an optimisation we should
utilise.
