summary: ensure seccomp rules for snap_daemon user work correctly
details: |
Snapd has limited capability to create a non-root accounts, so that certain
services that would normally run as root, perform initial configuration as
root but then drop to a less privileged user.
The test attempts to install a snap declaring to use a non-root user called
"snap_daemon". This name is allowed so the installation finishes
successfully and the new account is created on the system.
The test then continues to show that the resulting snap application indeed
has permissions to drop from the root user to the newly created account, by
effectively calling a number of related system calls with precise arguments,
checking both expected success and looking for violations where application
should stay contained.
