Subject: [PATCH] fix: replace duplicate libfftw3-dev with libfftw3-bin for
 SatDump runtime

The FFTW3 dev package was listed twice in the build stage and both
copies were removed during cleanup, taking the runtime .so with them.
Switching the duplicate to libfftw3-bin ensures libfftw3f.so.3 persists.

Fixes #166
