Change Details

Switch from Travis to Cirrus as a CI for libsecp256k1. Backport of secp256k1#864 The files have been adapted to match our codebase: - The build_autotools.sh and build_cmake.sh scripts are reused from the Travis setup. - The nixos base file is removed since it would build openjdk from source for i686 and time out. This is not a good move but these files will be removed in a follow-up diff anyway, so not a big deal. - Skip JNI tests on macOS, since Java is not installed on Cirrus macOS VM. - Work around valgrind install path not being searched by CMake. This is a known CMake issue (/usr/local/include should be part of the system search path for headers): https://gitlab.kitware.com/cmake/cmake/-/issues/19120 - Increase the timeouts, since we are running each test twice the valgrind task will not complete in 1h on macOS.
