Not for libcurl, since the libpq-oauth module split.

Ah, that's definitely a bug. I've tested alternate PKG_CONFIG_PATHs,
but I haven't regularly tested on systems that have no system libcurl
at all. So those header and lib checks need to be moved after the use
of LIBCURL_CPPFLAGS and LIBCURL_LDFLAGS to prevent a false failure.
Otherwise they're only useful for the LIBCURL_LDLIBS assignment.

I wonder if I should just get rid of those to better match the Meson
implementation... but the error messages from the checks will likely
be nicer than compilation failures during the later test programs. Hm.

(Thanks for the report!)
