tail: terminate when following pipes and untailable non pipes
* src/tail.c (ignore_pipe_or_fifo): Mark the descriptor as -1 for pipes so that any_live_files() detects correctly that the entry is no longer live. * tests/tail-2/pipe-f.sh: Add a test case. * NEWS: Mention the fix. Fixes http://bugs.gnu.org/24903 which was detected using Symbolic Execution techniques developed in the course of the SYMBIOSYS research project at COMSYS, RWTH Aachen University.
