This commit moves the timestamp computation of the control file within the routine of src/common/ in charge of updating the backend's control file, which is shared by multiple frontend tools (pg_rewind, pg_checksums and pg_resetwal) and the backend itself. This change has as direct effect to update the control file's timestamp when writing the control file in pg_rewind and pg_checksums, something that is helpful to keep track of control file updates for those operations, something also tracked by the backend at startup within its logs. This part is arguably a bug, as ControlFileData->time should be updated each time a new version of the control file is written, but this is a behavior change so no backpatch is done.
