sys-block/hpacucli forked, because #476640 takes too long

Changes:
 * Using /run/lock now instead of /var/run

 * "setarch" hack removed

 * Adjusted QA_PREBUILT value

 * QA_EXECSTACK added for libcpqimgr*.so to prevent QA notice we
   cannot fix
Outdated sys-boot/gnu-efi fork removed
net-firewall/shorewall*: Incorrect use of $PV in ebuilds corrected

Constanze pointed out to me that I've used $PV instead of $PVR.
This is now corrected, thanks!
