mount_linprocfs gone on CURRENT

[Tim Bishop]

Recently mount_linprocfs was removed on CURRENT. This breaks tinderbox
when building java/jdk15 (and probably some other things). I've tried
this simple fix to portbuild and buildscript and it worked fine for
java/jdk15:

	s/mount_linprocfs/mount -t linprocfs/

It looks like this should on other branches too, so could this change be
committed to tinderbox?

Tim.
