[OE-core] [PATCH 2/2] classes/buildhistory: use BB_CMDLINE to get bitbake command line

[Paul Eggleton]

We put the bitbake command line in the buildhistory commit message for
informational purposes, but calling sys.argv to get that as we were
previously doesn't really work in memory resident mode - that gives you
the command used to start the bitbake server which is much less
interesting. Use the just-introduced BB_CMDLINE variable instead.

Part of the fix for [YOCTO #11634].
