[LTP] [PATCH v2 1/1] lapi/io_uring: <sys/types.h> => <linux/types.h>

[Petr Vorel]

This fixes compilation on old toolchains:

Some old toolchains require to add <linux/types.h> to missing kernel
types:

tst_safe_io_uring.c: In function ‘safe_io_uring_init’:
tst_safe_io_uring.c:34:45: error: ‘__u32’ undeclared (first use in this function)
   34 |                 params->sq_entries * sizeof(__u32);
      |                                             ^~~~~

io_uring02.c: In function ‘drain_fallback’:
io_uring02.c:106:34: error: ‘__u64’ undeclared (first use in this function)
  106 |                 sqe_ptr->addr = (__u64)&spam_header;
      |                                  ^~~~~
io_uring02.c:106:34: note: each undeclared identifier is reported only once for each function it appears in
io_uring02.c: In function ‘run’:
io_uring02.c:221:26: error: ‘__u64’ undeclared (first use in this function)
  221 |         sqe_ptr->addr = (__u64)&beef_header;
      |                          ^~~~~

Newer kernel headers includes <linux/types.h> in <linux/io_uring.h>, but
we still support compilers without this header. Therefore replace
<sys/types.h> in lapi header with <linux/types.h>.

Fixes: 3f2ff5431 ("Add safe functions for io_uring to LTP library")
Fixes: c4f669f13 ("Add test for CVE 2020-29373")
