Subject: [PATCH 1/2] test: handle POSIX ioctl prototype

glibc has the following prototype for ioctl: int ioctl(int fd, unsigned long request, ...)
POSIX (inc. musl) has the following for ioctl: int ioctl(int fd, int request, ...)

Check which prototype is used in <sys/ioctl.h> to avoid a conflict and conditionally
define the right one for the system.
