Find wrong or local libraries using apt-file and output of ldd

# Program purpose:
#   analyze output of `ldd some-program` to find relevant packages in the configured APT repositories.
#   To ease the analysis one can run it with filter `$0 ldd_output | grep Warning` to get only missed libraries/packages.
#
# Note: having `linux-vdso.so.1` in the output is normal, it belong C library on the linker level.
