[LTP] [PATCH v2 00/33] Improve coverage for keyctl() syscall

[Andrea Cervesato]

Improve the keyctl() syscall coverage by adding more tests for the
following features, which are not currently tested in LTP:

- KEYCTL_DESCRIBE
- KEYCTL_GET_SECURITY
- KEYCTL_MOVE
- KEYCTL_RESTRICT_KEYRING
- KEYCTL_DH_COMPUTE
- KEYCTL_PKEY_*
- KEYCTL_CAPABILITIES
- KEYCTL_WATCH_KEY

The testing suite has been assisted by GLM 5.3 for coverage analysis
and Gemini Flash 3.7 for the tests skeleton.

Validation: https://openqa.opensuse.org/tests/6199954#
