base-files: add /run directory from FHS 3 draft specification

This adds the /run directory from the Filesystem Hierarchy Standard 3.0
Draft [1] and refactors the filesystem as follows:
- Remove creation of /var/volatile/run
- Remove creation of /var/volatile/lock
- Remove symbolic link from /var/run to /var/volatile/run
- Remove symbolic link from /var/lock to /var/volatile/lock
- Add symbolic link from /var/run to /run
- Add symbolic link from /var/lock -> /run/lock
- Add /run to /etc/fstab for sysvinit compatibility
