[LTP] [PATCH] syscalls/fsmount02: fix invalid-flags test failure on Linux 7.1+

[Avinesh Kumar]

Upstream Linux commit 5e8969bd1927 ("mount: add FSMOUNT_NAMESPACE") [1]
introduced the `FSMOUNT_NAMESPACE` flag, which maps to `0x02`.
This causes fsmount02 test failure as `0x02` value is no longer invalid.

fsmount02.c:56: TFAIL: invalid-flags: fsmount() succeeded unexpectedly (index: 1)

Use `0x80000000` as invalid flag value to adapt test for this upstream change.
