build: suppress an ignored-write-return-value warning
* bootstrap (modules): Add ignore-value. * src/guestfs.c: Include "ignore-value.h". (stdout_event): Ignore failure to write to stderr. Also, prefer STDERR_FILENO over the literal "2". * src/Makefile.am (libguestfs_la_CPPFLAGS): Include gnulib's .h files. (libprotocol_la_CFLAGS): Remove -Wall -Wno-unused.
