meson: Specify the maximum required libdrm in dri.pc

When dealing with a regression in libdrm-2.4.101, I masked the package
in Gentoo. In doing so, we discovered that Mesa's dri.pc specifies a
version requirement in dri.pc for >= the version of libdrm Mesa was
built against, thus preventing packages from being rebuilt with the
older version of libdrm installed.

Let's reduce this version requirement to the latest libdrm required by
Mesa instead, since libdrm is backward compatible.
