Merge #16926: depends: Add OpenSSL termios fix for musl libc

568aa0c Add OpenSSL termios fix for musl libc (Nathan Marley)

Pull request description:

  Currently the version of OpenSSL included in the depends system won't build on musl based systems because `termio.h` does not exist. The proper header named `termios.h` does exist.

  This PR adds a patch for OpenSSL to replace the `termio.h` header with `termios.h`, which is the proper POSIX header as I understand it.

  This is a known issue as `TERMIOS` (not `TERMIO`) should be the default, and is fixed in later versions of OpenSSL. There is discussion on the OpenSSL repo here: openssl/openssl#163

  This has been [fixed in OpenSSL](openssl/openssl@64e6bf6).

  This partly fixes #16925 and allows building Bitcoin on Alpine using the depends system.
