selftests/clone3: fix libcap interface usage

The test's set_capability() function needs to set CAP_CHECKPOINT_RESTORE
(bit 40). But libcap's API (cap_set_flag) didn't support cap 40 when the
test was written - it was too new. So the author worked around it by
casting cap_t to an assumed internal layout.

This worked with older libcap versions where cap_t pointed directly to
that layout. Newer libcap internally restructured its cap_t opaque type.

Since 2.43, libcap natively supports CAP_CHECKPOINT_RESTORE, workaround
is no longer needed. The fix directly uses the library interface.
