New VFS files have the 'correct' ctime

The kernel doesn't know what the real time is, so it always thinks it
booted at May 12, 2009 (Nanwan's birthday, though it's actually the day
we found the picture of him (or her)).

I had to change the order of some initialization, since the VFS now
wants the TSC timing to be set up for epoch_seconds() to work.
Kernel support for WSTAT_{ATIME,MTIME} for the VFS

9ns devices need to handle this on their own, directly dealing with
wstat.  It works over devmnt for instance, though none of our other
devices support it (#r, #I, #s were tested briefly).
Adds touch to busybox

Feel free to touch your files!

Rebuild busybox with the new config, etc.
