[Buildroot] [PATCH v2 1/1] linuxptp: new package

[Petr Kulhavy <brain@jikos.cz>]

Add the Linux PTP Project package.
http://linuxptp.sourceforge.net/

The sysV and systemd init scripts start the daemon in automatic mode on eth0.

Signed-off-by: Petr Kulhavy <brain@jikos.cz>

Changes v1 -> v2:
	- rename package from ptp4l to linuxptp
	- add EXTRA_LDFLAGS to the build cmd (suggested by Danomi Manchego)
	- sysV startup script: add restart/reload code, use PID file
	- clean-up empty lines and formatting issues
	- license uses SPDX license code
	- update DEVELOPERS file

+	help
+	  The Linux PTP Project is the Precision Time Protocol
+	  implementation according to IEEE standard 1588 for Linux.
+
+	  The dual design goals are to provide a robust implementation
+	  of the standard and to use the most relevant and modern
+	  Application Programming Interfaces (API) offered by the Linux
+	  kernel. Supporting legacy APIs and other platforms is not a
+	  goal.
