Remove the patchelf hack

The arm-elf-insight depends on libncurses5 while libncurses6 is installed by default.
Previously the dependecy was patched to use version 6 which is pretty bad.
Now libncurses5 is simply installed instead. Yes that package exists -_-
This also removes the need for the checksum.
