[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=2df6cf470397eae801e7f6ba9bfee88316a579b7
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The polkit daemon requires a polkitd user with permission to access the
following directories:
  - /etc/polkit-1
  - /usr/share/polkit-1

The /usr/bin/pkexec file must be owned by owned by root with the
permissions 4755 or else the error "pkexec must be setuid root" is
thrown when it's ran.
