libtraceevent: Add eof checks
Added checking for __read_char() and peek_char() to make sure value is not
at end of file.
This issue was found while fuzz testing. One of the test cases created an
infinite loop because __read_token had reached end of file. Checking was
added to all cases where this may occur.
