From 186206cff295de9afb0d1beda72a4304ebaa1e17 Mon Sep 17 00:00:00 2001

Subject: Allow specifying sysmocom headers explicitly

The headers for LC1.5 are specified explicitly. Add corresponding option
to specify sysmoBTS headers location and use it in jenkins build. While
at it, unify header fixup code with the one used in OsmoBTS.
