[ndctl PATCH v2 6/6] build: Add meson rpmbuild support

[Dan Williams <dan.j.williams@intel.com>]

Beyond being a prerequisite for removing autotools support, this capability
served as validation that the meson conversion generated all the same files
as autotools and installed them to the same expected locations.

The procedure to use the rpmbuild.sh script is:

    meson setup build
    meson compile -C build rhel/ndctl.spec
    ./rpmbuild.sh build/rhel/ndctl.spec
