Issue 312: added missing kernel mount options

Merged John Johansen requested to merge jjohansen/apparmor:apparmor-mnt-opts into master

This patch adds the following mount options: 'nostrictatime', 'lazytime', and 'nolazytime'.

The MS_STRICTATIME mount flag already existed, and 'nostrictatime' was listed along with 'strictatime' in the comments of parser/, so this patch adds a mapping for 'nostrictatime' to clear MS_STRICTATIME.

Additionally, the Linux kernel includes the 'lazytime' option with MS_LAZYTIME mapping to (1<<25), so this patch adds MS_LAZYTIME to parser/mount.h and the corresponding mappings in parser/ for 'lazytime' and 'nolazytime'.
