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

1.7.9.5

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].
