ci: Update meson requirement for DPDK.

The current version of meson used for building DPDK is 0.49.2.

This has the restriction of holding the required python version to 3.9.

A recent change [1] in DPDK bumped requirements on meson to 0.53.2.

Update the version of meson used to build DPDK to 0.53.2 to remove the
restriction.
