Subject: Add systemd unit files

Add bmcweb.socket, a systemd unit file that enables systemd socket
activation of bmcweb.  Systemd socket activation defers startup of
socket listening applications until something connects to the socket.
There are presently no configurable parameters in bmcweb.socket.

Add bmcweb.service, a systemd unit file for starting bmcweb.
bmcweb.service has one configurable parameter, the installation prefix.

Prior these unit files were hosted in the meta-phosphor repository but
OpenBMC is moving away from unit-files-in-metadata and trying to do it
the way the rest of the world does it - unit files are provided by the
projects that contain the application source.  The unit files were
copied mostly verbatim (minor update for installation prefix in
bmcweb.service template) so the only new logic here is in the cmake
logic.

Tested by:

1 - devtool add bmcweb.
2 - apply this diff to bmcweb_git.bb:

-inherit obmc-phosphor-systemd
+inherit systemd

3 - bitbake bmcweb.
4 - manual inspection of the image dir in the yocto build tree.
