rpm: Update spec for latest dependencies

SpeexDSP is now required.
Update the required cmake and glib versions.
Our CMake build process now expects a C++ compiler to always be present,
so require it even if not building the GUI.

Only default to Qt 6 on distributions where we know we have it,
otherwise default to Qt 5 for now.

Update the required RPM version to 4.13 (which all distributions that
can currently build have) to ensure we have Boolean dependencies.
Use Boolean dependencies instead of checking the distribution, hopefully
to improve building on various other RPM-based distributions.

Redefine the cmake_install macro on SUSE to what is used on RH/Fedora.
The default SUSE macro calls the builder (make or ninja) insted of
cmake --install, which makes it difficult to pass options.

Remove tests and workarounds for RHEL 7, and SUSE < 15.2, since those
distributions are too old to build anyway.
Remove a workaround for an old broken librotli-devel package in
SUSE that's been long since fixed.
