Merge #18145: build: add Wreturn-type to Werror flags, check on more Travis machines

6ba617dbe2b79d13ceec7d452e44ecab3bb814e7 build: add Wreturn-type to Werror flags (Sjors Provoost)
Pull request description:
I overlooked a missing `return false` in https://github.com/bitcoin/bitcoin/pull/17577#discussion_r379137776 and the warning only showed up on one Travis machine (`warning: control reaches end of non-void function [-Wreturn-type]`).
This PR promotes `Wreturn-type` to an error when configured with `--enable-werror`. I also added `--enable-werror` to the Travis machine that happened to catch this particular instance.
