Fix --onlydeps flag.

Browse Source 
When --onlydeps is specified, we don't want to merge packages that were
specified on the command-line. Previously, it threw an exception in this
case because it couldn't find the command-line packages in the list of
installed packages.

TEST=Run ./parallel_emerge --onlydeps autotest, and make sure it
     doesn't crash.
     Run ./parallel_emerge --board=x86-generic  -po chromeos power_manager and make sure it does emerge power_manager, and doesn't crash.
BUG=none
