Enable signature checking within build environment
* bind /sys and /dev/pts from host
* drop support for devtmpfs as it is no longer needed
* add /run and /dev/rtc0
* clone own ipc, uts and mount namespaces for chroot
* set localtime, timezone and locale within chroot environment
* copy /etc/pacman.d/gnupg from host
