Run pgindent on libpq's fe-auth.c, fe-auth-scram.c and fe-connect.c

A patch sent by Jacob Champion has been touching this area of the code,
and the set of changes done in a9e9a9f has made a run of pgindent on
these files a bit annoying to handle.  So let's clean up a bit the area,
first, to ease the work on follow-up patches.
