Restore initdb's old behavior of always setting the lc_xxx GUCs.

In commit3e51b27 I (tgl) caused initdb to leave lc_messages andother lc_xxx GUCs commented-out in the installed postgresql.conf fileif they were going to be set to 'C'. This was a hack for cosmeticpurposes, and it was buggy because lc_messages' wired-in default isnot 'C' but '' (empty string). That led to --no-locale not havingthe expected effect, since the postmaster would then obtainlc_messages from its startup environment.Let's just revert to the prior behavior of always de-commenting thelc_xxx entries; the argument for changing that longstanding behaviorwas weak in the first place.Also, fix postgresql.conf.sample's erroneous claim that the defaultvalue of lc_messages is 'C'. I suspect that was what misled me intomaking this mistake in the first place.Report and patch by Kyotaro Horiguchi. Back-patch to v16 wherethe problem was introduced.Discussion:https://postgr.es/m/20231122.162700.1995154567625541112.horikyota.ntt@gmail.com
