fix(bmcsetup): enable BMC setup for Lenovo SR635/SR655

The original Lenovo SR635/SR655 (IPMI manufacturer 19046, product 1287) use an
AMI "TSM" BMC reached over a LAN-over-USB interface, which needs OEM raw commands
to bring the interface up, select the LAN channel, and restart TSM networking
once configured. Add a dedicated vendor branch for it -- gated on the same
IPMIMFG/XPROD check the script already uses for IBM, Dell, Supermicro, OpenPOWER
and other Lenovo machines -- plus a udev rule and helper that bring up the USB
NIC (169.254.0.120) so in-band ipmitool can reach the TSM. The user-slot
auto-scan is skipped for these machines, which use a fixed slot.

Everything is behind IPMIMFG=19046 && XPROD=1287 (or the 046b:ffb0 USB device),
so no other BMC is affected.

Recovered from the unmerged lenovobuild branch (922dfe18, 42357f9d, 02da8a6b,
765e2ad3, 408cf2b3), adapted to master's bmcsetup structure. The global MD5 LAN
auth removal that rode along in 42357f9d is intentionally left out -- SR635/SR655
IPMI authentication is already handled in master by #7586 (retry cipher suite 3
on a zero RAKP2 HMAC), so dropping MD5 for all BMCs is neither needed nor wanted
here.

Not lab-validated: this targets the original SR635/SR655 (product 1287); no such
machine was available to test (an SR635 V3 reports product 1601 and uses a
different, directly-reachable BMC). The code is gated so it cannot affect other
hardware.
