Now it's enabled by default for X86_64.

Now functional_test.sh is a common script used both in GitHub Actions
and Woodpecker-CI.

And also test the forgotten .gz kernel config.

We need to check them because these kernel cmdline parameters can
override the COMPAT_VDSO kconfig option.

CONFIG_COMPAT_VDSO disabled ASLR of vDSO only on X86_64 and X86_32.
On ARM64 this option has different meaning (see the mainline commit
7c4791c9efca8c105a86022f7d5532aeaa819125).

Disabling X86_VSYSCALL_EMULATION turns vsyscall off completely, and
LEGACY_VSYSCALL_NONE can be changed at boot time via the cmdline parameter.

Thanks to @izh1979 for the idea

Use new override_expected_value() for that.

This is needed to avoid wrong recommendations for ARM64 and ARM, where
CONFIG_ARCH_MMAP_RND_BITS_MAX depends on the paging configuration.

SELinux, Smack, Tomoyo, and AppArmor implement Mandatory Access Control (MAC).

Thanks to @izh1979 for the idea

The CONFIG_CORESIGHT framework provides a kernel interface for the
CoreSight debug and trace drivers for ARM/ARM64. It's better to have it
disabled to cut attack surface.

CONFIG_INTEGRITY is useless without enabling IMA/EVM.
We can't require enabling IMA/EVM because there are other
file system integrity mechanisms like DM_VERITY, FS_VERITY, etc.
So there is no reason to check CONFIG_INTEGRITY.

Refers to #75

Also rename old Android configs

It's refactoring, no functional changes

I mean testing 'is present' and 'is not off' in OR/AND
