bitbake.conf: set an exclusion list for varflags in checksums

Set BB_SIGNATURE_EXCLUDE_FLAGS, which is used by the new varflag
checksum code in BitBake. The list is intended to cut out most of the
varflags that are generated internally, don't influence the output or
are already included in the checksum in some way. If need be this list
can be extended in the future. The existing vardepsexclude mechanism
can also be used to exclude undesired varflags, but they must be fully
specified, e.g.:

do_patch[vardepsexclude] += "do_patch[someflag]"

Implements [YOCTO #2517].
