    firmware/shim: update linkfarm exclusions
    
    Some intermediate files weren't considered at all at the time. Also
    after its introduction, various changes to the build environment have
    rendered the exclusion sets stale. For example, we now have some .*.cmd
    files in the build tree. Combine all respective patterns into a single
    .* one, seeing that we don't have any actual source files matching this
    pattern in the tree. Add other patterns as well as individual files.
    Also introduce LINK_EXCLUDE_PATHS to deal with entire directories full
    of generated headers as well as a few specific files the names of which
    are too generic to list under LINK_EXCLUDES.
