dist/common/scripts: support nonroot mode on setup scripts

Since nonroot mode requires to run everything on non-privileged user,
most of setup scripts does not able to use nonroot mode.
We only provide following functions on nonroot mode:
 - EC2 check
 - IO setup
 - Node exporter installer
 - Dev mode setup
Rest of functions will be skipped on scylla_setup.
To implement nonroot mode on setup scripts, scylla_util provides
utility functions to abstract difference of directory structure between normal
installation and nonroot mode.
