Subject: [PATCH] conf: include signal.h for str2sig() and SIGHUP

The reload-signal translation calls str2sig() and compares against
SIGHUP, but conf.c never included signal.h.  glibc pulls it in
transitively, so the omission went unnoticed until a cross-compile
against uClibc-ng in Buildroot failed to build.
