[Bug 1294618] [NEW] plymouthd sets first char of proc title to '@'

[James Hunt]

Public bug reported:

When plymouthd is running, it's /proc/$pid/cmdline shows argv[0] as
'@sbin/plymouthd'.

Running plymouthd without specifying the path sets cmdline to
'@lymouthd' so it is over-writing the first character of its argv[0].
