Since upstream commit dc92994 the LDFLAGS used for settings the version
(and build host and user) changed resulting in "unknown" versions in
syncthing.

Correct version detection is important for syncthing to assure
compatibility with other running instances. The "unknown" version fails
to communicate and sync with correctly compiled instances.

This patch updates the syncthing Makefile to inject the correct
variables and thereby fixes the version detection in syncthing.

Added the ability to enable/disable via a config file;
the default is enabled for backwards compatibility.

This is an additional service, so running it the
same priority as dnsmasq, etc does not make sense.

Added USE_PROCD=1

"done" starts at "START=95", so this should start earlier

Added STOP=10 to stop syncthing early
