[PATCH] pgrep: fix -a without -f

[Alyssa Ross]

If I run the following:

	sleep inf &
	pgrep -a sleep

I'd expect a result like:

	./busybox pgrep -a sleep
	3955 sleep inf

(That's the result I get from procps's pgrep.)
But prior to this patch, I'd actually get:

	./busybox pgrep -a sleep
	3955 sleep

This happened because the processes' full argv was only being read if
-f was passed, but -a also needs it to be read so it can print it.
