gh: pin libuv package to 1.52.1 on cygwin and msys jobs

Since Cygwin and MSYS2 updated their libuv package to 1.53.0, the
install testsuite of the cygwin and msys jobs hangs until the 6 hour
job limit cancels it. This libuv version switches process spawning on
Unix from fork to posix_spawn, which cmake relies on for
execute_process. Only the install testsuite runs the cmake
initialization script, which explains why the build testsuite still
passes. Pin libuv to its previous version on both jobs until the issue
is resolved upstream.
