Fix README files and remove stale config.guess and config.sub

README.Unix.txt and README.Windows.txt (MinGW, MSYS) instructed to
execute `NOCONFIGURE=1 ./autogen.sh` which is no longer necessary
(a simple `autoconf` does the job).

Remove files misc/config.guess and misc/config.sub because they are
no longer needed: these files are now in th FLTK root directory
available. Remove all references to these files.

Fix .gitattributes accordingly. Also exclude the .github folder
from exports, for instance when creating distribution tarballs.

+# Just run `autoconf` instead to generate `configure` and you're done.
+#
+# The old README.Unix.txt stated that it should be executed from within
+# the "FLTK source-code directory", hence changing directories is not
+# useful and would break if the user's home directory contained spaces.
+# Changing directories has been removed in FLTK 1.4.0 and this file
+# has been simplified substantially.
+#
+# Instead of executing it as documented in pre-1.4 README files the new docs
+# instruct to just execute `autoconf` which is sufficient and equivalent to
+# the old instructions.
