Roland Kaufmann e4a345a648 Use OPM_MACROS_ROOT to locate build scripts
By using a separate variable for this we can easily grep for where
the build system depends on its own location, and also change the
policy regarding this later.

Note that there is no opm-macros module; this is a "psuedo"-module
which links to an additional one (currently, the one we're in)
