[PATCH] lib/test_sysctl: support testing of sysctl. boot parameter - fix

[Vlastimil Babka]

Skip the new test if boot_int sysctl is not present, otherwise, per Luis,
"This would fail if someone uses this script to test an older kernel, and
the scripts in selftests are supposed to work with older kernels."
