lseek: avoid bash 3.2 broken pipe bug

Avoid a spurious message caused by SIGPIPE handling, as well as
avoiding bash 3.2 messages even when SIGPIPE is not handled.

* m4/lseek.m4 (gl_FUNC_LSEEK): Drain pipe, to avoid spurious
warning from bash 3.2.
Reported by Ben Pfaff, with analysis from Bruno Haible.
