    openssl.inc: avoid random ptest failures
    
    "make alltests" is sensitive to the timestamps of the installed
    files. Depending on the order in which cp copies files, .o and/or
    executables may end up with time stamps older than the source files.
    Running tests then triggers recompilation attempts, which typically
    will fail because dev tools and files are not installed.
    
    "cp -a" is not enough because the files also have to be newer than
    the installed header files. Setting the file time stamps to
    the current time explicitly after copying solves the problem because
    do_install_ptest_base is guaranteed to run after do_install.
