parallel_emerge: Work around Portage library bug with usepkg
When using --usepkg, the Portage library imported into parallel_emerge
will always return "optional" instead of "buildtime" as the deptypes
even when a package is being built from source (ie. the binary package
is not available or an uprev is occuring). This has caused years of
frustration and loathing for the DEPEND and RDEPEND variables.
This works around the problem by always treating 'optional' as a
strong package dependency when usepkg is enabled.

TEST=./setup_board for previously failing board, ./build_packages to
confirm that non-determinism in package install order is gone. (And
that coreboot builds as expected.)
