Use close_range(2) in closefrom() emulation if available.

On Linux, prefer our own closefrom() emulation since the glibc
version may fail if /proc is not present and close_range() is not
supported. On FreeBSD, closefrom(3) will either call the closefrom
or close_range system call, depending on which is available.

Change intercept IPC to use a localhost socket instead of inherited fd.
...
This allows intercept mode to work with shells that close all open
fds upon startup. The ctor in sudo_intercept.so requests the port
number and secret over the socket inherited from the parent then
closes it. For each policy request, a TCP connection is made to
the sudo parent process to perform the policy check. Child processes
re-use the TCP socket to request the port number and secret just like
the initial process started by sudo does.

Use TLS_method() instead of TLS_client_method() throughout.
...
OpenSSL returns an error for SSL_accept() if TLS_client_method()
was used to generate the context (LibreSSL doesn't care).
Prior to sudo 1.9.7, TLS_client_method() and TLS_server_method()
were used in the TLS client and server initialization code respectively.
This was refactored in sudo 1.9.7 to allow the code to be shared.
