[LTP] [PATCH] ioctl_ficlone03: fix capabilities on immutable files

[Andrea Cervesato]

From: Andrea Cervesato <andrea.cervesato@suse.com>

Make sure that capabilities requirements are satisfied when accessing
immutable files. On OpenSUSE Tumbleweed 32bit bcachefs fails with the
following error due to missing capabilities:

tst_test.c:1833: TINFO: === Testing on bcachefs ===
..
ioctl_ficlone03.c:74: TBROK: ioctl .. failed: ENOTTY (25)
ioctl_ficlone03.c:89: TWARN: ioctl ..  failed: ENOTTY (25)
ioctl_ficlone03.c:91: TWARN: ioctl ..  failed: ENOTTY (25)
ioctl_ficlone03.c:98: TWARN: close(-1) failed: EBADF (9)

Introduce CAP_LINUX_IMMUTABLE capability to make sure that test won't
fail on other systems as well.
