mm:kallsyms from ubuntu_ltp failed

[LEE KUAN-YING]

[Impact]
The updated LTP(new version as listed below) has added kallsyms testcase which can't pass
since CONFIG_KALLSYMS isn't enabled in KVM kernel.

Old LTP version:
Latest commit in 'sru' branch: 58aa31f55 UBUNTU: SAUCE: Upstream head SHA1 cbc2d05684
Latest upstream commit: cbc2d0568 mkdir03: Convert docs to docparse

New version:
Latest commit in 'sru' branch: bdcd2254e UBUNTU: SAUCE: Upstream head SHA1 8f21ebba42
Latest upstream commit: 8f21ebba4 LTP 20240524

[Regression potential]
Low risk since these testcase is new.

Fix applied upstream and pulled back to our fork, this is no longer failing on B/kvm and X/kvm. Hints removed.
Thanks.
