libserialport: add patch so it doesn't use termiox

termios has been removed from recent kernels, so not having this patch
causes "no such ioctl for device"-errors, preventing any use of the
library

+Inspired by this commit from the upstream package:
+https://sigrok.org/gitweb/?p=libserialport.git;a=commit;h=6f9b03e597ea7200eb616a4e410add3dd1690cb1
+
+Applying this patch directly added some extra dependencies (autoconf,
+automake), as the configure script needs to be regenerated with the
+original commit.
+
+original commit message:
+
+termiox was removed from linux in e0efb3168d34
+Some more information available in https://www.spinics.net/lists/linux-serial/msg41926.html
+
+Attempting to use the termiox ioctls on more modern kernels results in
+"Inappropriate IOCTL" errors.
+
+While the "right" solution might be to remove the termiox code from the
+linux path, simply not checking for termiox builds a libserialport that
+functions on modern linux kernels.
