Revert "t0081 (line-buffer): add buffering tests" 

This (morally) reverts commit d280f68313,
which added some tests that are a pain to maintain and are not likely
to find bugs in git.

test_description="Test the svn importer's input handling routines.
These tests exercise the line_buffer library, but their real purpose
is to check the assumptions that library makes of the platform's input
routines. Processes engaged in bi-directional communication would
hang if fread or fgets is too greedy.
These tests provide some simple checks that the line_buffer API
behaves as advertised.
While at it, check that input of newlines and null bytes are handled
correctly.
