staging.bbclass: handle postinst-useradd-* fixmes
After
02457ef7f600ce954874e2d11e74b1c6daaa3bfc, PSEUDO for
postinst-useradd-* scripts get to use only one PSEUDO_LOCALSTATEDIR
which is set under recipes ${WORKDIR}.
When the those scripts are run in a clean build environment that
is built from the sstate (populate_sysroot_setscene run for
postinst-useradd-* providers), pseudo fails to run because it cannot
access the PSEUDO_LOCALSTATEDIR (recipe ${WORKDIR}s do not exist).
This triggers a sysroot staging error.
Previously, the PSEUDO_LOCALSTATEDIR setting in useradd.bbclass
worked because the RSS sstate/staging logic automagically processed
${STAGING_DIR_TARGET} in postinst-useradd-* scripts to point under
the sysroot being built.
The fix uses the same fixme processing by adding PSEUDO_LOCALSTATEDIR
variable to it. Furthermore, LOGFIFO is added to be able to use
the logging fifo of the recipe that actually runs postinst-useradd-*.
