build: Remove redundant comparisons

If a Meson option is typed as `boolean`, the `get_option` returns a
boolean, and comparing it with `true` is redundant. Meson also errors if
you try to compare across types, so it couldn't _not_ be a boolean.

Also, Meson is not C, so no need for parentheses around `if` conditions.
