[PATCH v1 1/2] security: Allow 'remember' to be set for HostdevLabelHelper

[Daniel Henrique Barboza <danielhb413@xxxxxxxxx>]

There is a case in which we do not want 'remember' to be
set to true in SetOwnership() calls inside the
HostdevLabelHelper() functions of both DAC and SELinux drivers.
Next patch will explain and handle that scenario.

For now, let's make virSecurityDACSetOwnership() and
virSecuritySELinuxSetHostdevLabelHelper() accept a 'remember'
flag, which will be used to set the 'remember' parameter
of their respective SetOwnership() calls. No functional
change is made.
