Subject: cleanup mysql_install_db

1. detect resolveip location, don' assume it's in $basedir/bin
2. don't guess $scriptdir to (incorrectly) construct the $0 path
3. rename find_in_basedir -> find_in_dirs, don't prepend $basedir
   automatically. This allows to use identical path lists in
   find_in_dirs and in cannot_find_file.
4. move search path lists to CMakeLists.txt to avoid specifying the
   same path list twice (in find_in_dirs and in cannot_find_file).
