quote: rename misnamed sq_lookup[] to cq_lookup[]

gitster · gitster · commit dfc7f65c261e · 2020-09-10T13:07:24.000-07:00
This table is used to see if each byte needs quoting when responding
to a request to C-quote the string, not quoting with single-quote in
the shell style.  Similarly, sq_must_quote() is fed each byte from
the string being C-quoted.

No behaviour change intended.
