NQP::Config missing from release tarball

[mojca]

Building nqp 2019.07.1 from release tarball no longer works (2019.03 worked; I didn't check intermediate versions):

After fetching https://github.com/perl6/nqp/releases/download/2019.07.1/nqp-2019.07.1.tar.gz instead of https://github.com/perl6/nqp/archive/2019.07.1.tar.gz, the build seems to work.
