pocketsphinx: Add version 5.1.1 (#2322)

Build pocketsphinx from the upstream v5.1.1 checkout with cibuildwheel on
the riscv64 manylinux image, running upstream's pytest suite against each
wheel. The wheel also carries the MT19937, dtoa and yin notices, which are
compiled in but missing from upstream's LICENSE.
