Fix Debian x64 build: drop nonexistent libwlroots-dev, build wlroots 0.19.1 without -Werror

Browse source 
Debian >= trixie packages wlroots versioned (libwlroots-0.20-dev,
pkg-config wlroots-0.20), which falls outside the >=0.19,<0.20 pin, so
the bundled 0.19.1 source build is used. Fix the README apt line
accordingly and build the wlroots subproject with werror=false so the
newer libinput (1.31.3) enum LIBINPUT_SWITCH_KEYPAD_SLIDE is only a
warning, not a fatal -Werror=switch error.

`libwlroots-dev` already satisfies the wlroots dependency on this platform.
No wlroots package is needed: this project targets wlroots 0.19, while
Debian/Ubuntu ship another version as a versioned package (e.g.
`libwlroots-0.20-dev` on Debian >= trixie, pkg-config name `wlroots-0.20`),
so Meson builds the bundled 0.19.1 instead (see below).

The Meson setup searches for `wlroots-0.19` then `wlroots`; if neither is
installed it builds the pinned 0.19.1 from `subprojects/wlroots.wrap`, which
only needs the wayland, wayland-protocols, xkbcommon and EGL/GLES2 dev

packages listed above. On newer Debian/Ubuntu the packaged wlroots is a
versioned library (e.g. `libwlroots-0.20-dev`, pkg-config `wlroots-0.20`)
whose version falls outside this project's `>=0.19,<0.20` pin, so the
fallback build is used automatically and no wlroots package needs to be
installed. Optional wlroots features (Vulkan, X11, libinput, etc.) are
