[PATCH v2 2/3] psplash: work on first boot (sysvinit)

["Trevor Woerner" <twoerner@gmail.com>]

The psplash program has a mechanism for showing progress/updates. This
is done via a pipe. On images that are R/O or images that are assembled
via wic, the pipe is being setup in a location that is R/O on first boot,
therefore the pipe can not be created. If the psplash program is not able
to create the pipe, the app will not run. This situation is "fixed" on
non-R/O images when the first bootup is complete. Therefore the psplash
program is able to run for the first shutdown, and all subsequent bootups
and shutdowns as well, but not on the very first boot.

If the directory in which the psplash pipe is to be created already exists in
the filesystem and that location is not R/O on first boot, then the psplash
program can run on first boot (and subsequent boots and shutdowns).

NOTE: this is only an issue with sysvinit and most non-qemu machines. A
systemd image, and images run on qemu machines, are able to run psplash on
the first and subsequent boots.
