systemd: rename service file to align with repo name

Updated systemd service file as following for better readability
start-ipkvm.service -> obmc-ikvm.service

Testing:

Verified systemd service using QEMU + AST2600EVB firmware.

Before changes:

root@evb-ast2600:~# systemctl status start-ipkvm
* start-ipkvm.service - OpenBMC ipKVM daemon

After changes:

root@evb-ast2600:~# systemctl status obmc-ikvm
* obmc-ikvm.service - OpenBMC ipKVM daemon
