When installing the decompiler, do not remove the entire share dire…

…ctory (avast#12).

Remove only the subdirectories and files that are used by RetDec. This should
reduce the chance of unintentionally removing system directories when RetDec is
accidentally installed on Linux into e.g. `/usr` as the `arm`, `generic`, and
`x86` directories are not commonly used by Linux distributions.

Nevertheless, as mentioned in our README, until our build system properly
supports system-wide installations, RetDec should to be installed into a clean,
dedicated directory.
