meson.build: drop listing of header files from compilation targets

"Meson uses Ninja which uses compiler dependency information to
automatically figure out dependencies between C sources and headers, so
it will rebuild things correctly when a header changes. [...]
If, for whatever reason, you do add non-generated headers to the sources
list of a target, Meson will simply ignore them."
