[OE-core] [PATCH] buildhistory.bbclass: do not influence sstate of do_rootfs

[Patrick Ohly]

Enabling or disabling buildhistory caused a rebuild of images, which
is undesirable. For example, it prevented image reuse from a main
build with buildhistory in a following oe-selftest where buildhistory
must be disabled.

The reason are the additional ROOTFS_POSTUNINSTALL_COMMAND and
ROOTFS_POSTUNINSTALL_COMMAND entries. Those need to be excluded both
via vardepvalueexclude and vardepsexclude.
