Re-format ld.config.*.txt files

Re-format the files by splitting lines using +=.

Also add /odm/${LIB} where needed.

A few directories that are no longer required are removed from the
search paths and permitted paths.

Test: walleye and sailfish boots to the UI, renderscript, camera,
camcodder, sound, etc. are working.
