bolt plan run peadm::install fails is umask is not set to 022

[tuxmea]

Describe the Bug

When setting umask to e.g. 027 several directories gets created without the required work access bit set.
This causes the installer to fail on running postgresql initdb

Expected Behavior

peam::install knows about umask issues and sets them accordingly prior starting the PE installer

Steps to Reproduce

Steps to reproduce the behavior:

1. set umask (system wide) to 027
2. run peadm::install plan (fresh installation)

Environment

• Version latest and PE 2021.7.2
• Platform Ubuntu 20.04
