webos_ls2_conf_validate.bbclass: Skip do_validate_ls2_acg if sysbus d…

…irectories don't exist

:Release Notes:
Skip running do_validate_ls2_acg if any of sysbus directories needed
does not exist.

:Detailed Notes:
Sysbus directories are essential but we need this check for some variant
like core-boot in Apollo.

:Testing Performed:
Set up a core-boot profile in build-apollo and ran
bitbake <image> -c do_validate_ls2_acg

:QA Notes:

:Issues Addressed:
[WRQ-2420] CCC: Skip do_validate_ls2_acg if sysbus directories don't
           exist
[WRQ-1154] Check ACG groups used but not defined at buildtime
