remove brp-20-check-la, test is broken and la files are mostly deleted anyway
add some double quotes into brp-45-tcl
brp-50-check-python: add some double quotes, remove commented code
brp-60-hook: add some double quotes
brp-40-rootfs: speed-up of the script

by removing the loop from the bash but instead doing some little
modifications using sed (brp-rootfs.data/ldd.sed)
