meson: sync programmer dependencies from Makefile

The Makefile recently gained finer-grained programmer dependency lists
allowing it to track which enabled programmers assume various things
about the system, like availability of libraries or the CPU
architecture. This change implements the same changes in the Meson
configuration file.

This fixes a number of programmers to correctly build on non-x86
systems, because they were previously misclassified as dependent on x86
architectural features but actually only used PCI.

BUG=none
TEST=meson build succeeds on both x86 and ARM
