Useful tools missing from /rescue

[Yar Tikhiy]

Hi all,

I've had to use /rescue recently and felt lack of a few basic tools
in it, namely pgrep(1), head(1), tail(1), tee(1), and a text filter,
e.g., sed(1).  Well, in fact most functionality of pgrep(1), head(1),
tail(1), and even tee(1) can be emulated if one has sed(1), but the
tools are so tiny and convenient that it's a pity not to have them
all handy during hard times.

In addition, there are chflags and chmod in /rescue, but there's
no chown in it, so the toolset is a bit incomplete.

Would anyone mind if I add those tools to /rescue?  The size growth
will be rather small:

-r-xr-xr-x  121 root  wheel  3715096  1 сен 10:22 /mnt2/rescue.old/rescue
-r-xr-xr-x  129 root  wheel  3761828  1 сен 11:22 /mnt2/rescue/rescue

The patch is attached.

Thanks!
