Avoid compiler warnings due to ignored write return values
Glibc (at least) provides the warn_unused_result attribute on write,
(if optimizing and _FORTIFY_SOURCE is defined). So we explicitly
ignore the return value in our signal handler, where we couldn't do
anything anyway.
Compile with:
make CFLAGS="-O -D_FORTIFY_SOURCE"
before this commit to see the warning.
