BaseTools: Fix raw strings containing valid escape characters

Fixes raw regex strings that contain valid (and purposeful) escape
characters as they are being treated as individual characters rather
than the single escaped character they represent (i.e. '\t' is being
treated as a '\' and a 't' rather than a single tab character).
