build_reloc.sh: Remove "--with" passed to "configure.py"
build_reloc.sh: Remove "--with" passed to "configure.py"

The build_reloc.sh script passes "--with=scylla" and "--with=iotune" to
the configure.py script. This is redundant as the
"scylla-package.tar.gz" target of ninja already limits itself to them.

Removing the "--with" options allows building unit tests after a
relocatable package has been built without having to rebuild anything.
