Martin Roukala (né Peres) f4c81b0aa5 Only prevent VTs to be mounted inside privileged systemd containers ...

While mounting virtual console devices in a systemd container is a
recipe for disaster (I experienced it first hand), mounting serial
console devices, modems, and others should still be done by default
for privileged systemd-based containers.

v2, addressing the review from @fho:
 - use backticks in the regular expression to remove backslashes
 - pre-compile the regex at the package level
 - drop IsVirtualTerminalDevice (not needed for a one-liner)

v3, addressing the review from @fho and @rhatdan:
 - re-introduce a private function for matching the device names
 - use path.Match rather than a regex not to slow down startup time

Closes #16925.
