tests: fix ioctl_dm test with new kernel headers
Linux commit v5.19-rc2-1-g94dfc73e7cf4 replaced the zero-length array
dm_target_msg.sector field declaration with a flexible-array declaration,
which led to the following error when compiled with clang:
../../../tests/ioctl_dm.c:53:25: error: field 'target_msg' with variable
sized type 'struct dm_target_msg' not at the end of a struct or class
is a GNU extension [-Werror,-Wgnu-variable-sized-type-not-at-end]
struct dm_target_msg target_msg;
^
1 error generated.
Work around it by removing the following field and adjusting
the untyped message size.
* tests/ioctl_dm.c (struct s): Remove tm.target_string field, adjust
string field size.
