pg_restore: add --no-globals option to skip globals

This is a followup to commit 763aaa06f03 Add non-text output formats to
pg_dumpall.

Add a --no-globals option to pg_restore that skips restoring global
objects (roles and tablespaces) when restoring from a pg_dumpall
archive. When -C/--create is not specified, databases that do not
already exist on the target server are also skipped.

This is useful when restoring only specific databases from a pg_dumpall
archive without needing the global objects to be restored first.

With small tweaks by me.
