Make pg_upgrade log message with control file path translatable.

Make pg_upgrade log message with control file path translatable.

Commit 173c97812ff replaced the hardcoded "global/pg_control" in pg_upgrade
log message with a string literal concatenation of XLOG_CONTROL_FILE macro.
However, this change made the message untranslatable.

This commit fixes the issue by using %s with XLOG_CONTROL_FILE instead of
that literal concatenation, allowing the message to be translated properly.
It also wraps the file path in double quotes for consistency with similar
log messages.
