openssh/rc-once: use fixed string grep to match filename
This is a (very) minor optimisation. There is no semantical change as
the fixed list of possible filenames doesn't contain anything that has a
different meaning when interpreted as a regex, still I consider it
better style to interpret the filename as a fixed string to match.
Both busybox and the "big" grep support -F unconditionally so there is
no problem in using -F.
