Add missing Linux libraries to build.sh

[KeatonTheBot]

Add Linux libraries libjack and libusb to build.sh. The latter fixes an issue with the Nintendo Switch 2 Pro Controller, as outlined here: Ryubing/Issues#318.

I've looked through the linked issue and the downstream PR, but it wasn't mentioned how this fixes the issue. Do you know the mechanism of how including these libraries fixes the problem? Will those libraries be a hard pre-requisite for end-users with this change?

According to these variables, libusb is an optional dependency:
SDL_HINT_HIDAPI_LIBUSB
SDL_HINT_HIDAPI_LIBUSB_WHITELIST

Seems probably okay to me? @Susko3 will leave the merge in your hands

Also looks fine to me. If this breaks stuff for users, they can disable it with the hint.
