meson: Avoid the creation of extra variables

Extra variables are used for sources of targets in the `dispatcher`
build file. These have been moved to the `source` parameter because
using them directly avoiding the creation of extra variablse doesn't
hurt readibility.

The compiler flags `cflags` variable has also been renamed to be
consistent with the rest of build files.
