[PATCH 01/10] Support systems that do not have /boot as a separate filesystem

[Cleber Rosa <crosa@xxxxxxxxxx>]

While testing grubby on systems with a root (/) filesystem that includes
the /boot directory, it was noticed that grubby displayed the prefix (/boot)
twice.

This patch prevents printing the prefix twice on kernel and initrd lines.
