Subject: [PATCH] signal/cbindgen.toml: add stdint.h to sys_includes for
 signalfd_siginfo types

The signalfd_siginfo struct uses uint32_t, int32_t, uint64_t, uint16_t
which require <stdint.h>. Without it, gnulib-based packages (m4, bison,
flex) fail configure's sigset_t test because signal.h doesn't compile.
