x11/x3270: update to version 4.2ga10

Improvements:

    Modified the ./configure script to be able to find the macOS installations \ 
of OpenSSL from Homebrew and MacPorts.

Bug fixes:

    TN3270E NVT mode now works properly.
    TN3270E SSCP-LU mode now works even if BIND-IMAGE has not been negotiated by \ 
the host.
    When TN3270E is turned off and back on within a session, x3270 now \ 
renegotiates functions properly.
