util: Remove dependency check

The list is rather old and it contains some entries which are likely
unneeded. Since we are also now able to select specific FS binaries
to be compiled individually, there is not point of requiring all
components to be installed.
Instead, if is better to rely on the error message of building process
and let the users figure out which packages they need to install
