v4l2: Fix compilation of __open_2() and __openat_2() with gcc
The __open_2() and __openat_2() functions are defined by glibc as taking 2 and 3 arguments respectively, with variadic arguments for the file mode as open() and openat() do. The V4L2 compatibility layer defines them as aliases for open() and openat(), which results in compilation failures with gcc: ../../src/v4l2/v4l2_compat.cpp: In function ‘int __openat_2(int, const char*, int)’: ../../src/v4l2/v4l2_compat.cpp:58:14: error: invalid conversion from ‘int’ to ‘const char*’ [-fpermissive] 58 | return open(dirfd, path, oflag); | ^~~~~ | | | int ../../src/v4l2/v4l2_compat.cpp:31:39: note: initializing argument 1 of ‘int open(const char*, int, ...)’ 31 | LIBCAMERA_PUBLIC int open(const char *path, int oflag, ...) | ~~~~~~~~~~~~^~~~ ../../src/v4l2/v4l2_compat.cpp:58:21: error: invalid conversion from ‘const char*’ to ‘int’ [-fpermissive] 58 | return open(dirfd, path, oflag); | ^~~~ | | | const char* ../../src/v4l2/v4l2_compat.cpp:31:49: note: initializing argument 2 of ‘int open(const char*, int, ...)’ 31 | LIBCAMERA_PUBLIC int open(const char *path, int oflag, ...) | Fix this by defining the two functions as wrappers around open() and openat() without variadic arguments.
