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
