pleroma/otp: invite-only by default; fix tzdata write-permission crash loop

Default pleroma_signup_open to "false" and add pleroma_invites_enabled
"true" as a default (there was none before, every instance had to set it
explicitly). Two of three live instances were already overridden to
invite-only; open registration by default is what let haskell.social get
hit by spam/harassment in the first place.

Point tzdata's :data_dir at a writable, per-instance directory instead of
its own root-owned lib path. Without this, tzdata_release_updater crashes
every few seconds trying to write its update-poll marker file under
/opt/pleroma/lib, which the pleroma user can't write to.
