v4l2: v4l2_compat: Fix ioctl() prototype with musl C library
The musl C library, as well as the POSIX standard, define the ioctl() function's request argument as an int. glibc and uclibc, on the other hand, define it as an unsigned long. This difference between the function prototype and the implementation in the V4L2 adaptation layer causes a compilation error with musl. Fix it by detecting the function prototype and declaring the libcamera ioctl() handler accordingly.
