posix: sys/stat.h: adopt the sys/stat.h header from picolibc
This may be getting ahead of the curve a bit, but here we adopt the `<sys/stat.h>` header from picolibc. It is mostly the same as that of newlib but the picolibc variant seemed to be slightly more "inclusive". Removed the `<_ansi.h>` include. The commit immediately following this declares a few missing types only if they are not already declared. Signed-off-by: Chris Friedt <[email protected]>
