[v2,3/4] selinux: Standardize string literal usage for selinuxfs directory names

Commit Message

Daniel Burgener Aug. 12, 2020, 7:15 p.m. UTC

Switch class and policy_capabilities directory names to be referred to with
global constants, consistent with booleans directory name.  This will allow
for easy consistency of naming in future development.
