Remove Triple Vendor check when creating Linux Platform

[ted]

Summary

The Linux Platform shouldn't care about the Vendor field in the Triple. Currently it allows a value of "PC", or "unknown" if LLDB was built on Linux. This patch removes that check, so the Vendor field isn't touched. This will allow the Linux Platform to be created when using a Triple of *-*-Linux.

Looks good.

This is good. Had some issues with this in the past.

LGTM (you don't have to wait for an approval from @vharron)
