added explicitly because despite it being a default, fft doesn't seem to work.

As you can see, fft doesn't work, and the fftw delegate isn't listed as a built-in.
Unsure if this would work, as I am unable to configure a termux build environment (my pc is >10 years old, not powerful enough for android build environments; the build scripts don't seem to want to work on my tablet)
regardless of upstream activity which is a shortcoming of
termux_git_clone_src.sh that currently always choose the latest commit from
the repo. The issue is spotted in 1337fa0ffe9cd1e3813921dc5b53b0fd1d8f904b.
Also updates the package for clvk and bump the revision for clpeak.
Cancel Gitea update for now due to error in one of dependencies,
maybe need wait 1.15.7+.
