terminal: change license to LGPL

All authors of the current code have agreed.

The code probably originates from a software named GySmail (as the
copyright header indicates). As far as I can tell, it was written by
Arpi (who has agreed), possibly with unknown co-authors. This is most
likely OK, as none of the original code is around anymore anyway. I
could not find a working download of GySmail, that actually contained
the original getch2.c code.

This also has a wild history of random people adding ifdef guards to
control ioctl() vs. tcgetattr() calls. (See for example 2b1310abba4c1.)
Later, the ioctl() was removed in favor of the POSIX tcgetattr(), and
the ifdeffery was removed. So these people were not contacted.
