doc: update description about user/group in qemu.conf

As a side effect of changes in the functions virGetUserID and
virGetGroupID, the user and group configurations for DAC in qemu.conf
are now able to accept both names and IDs, supporting a leading plus
sign to ensure that a numeric value will not be interpreted as a name.

This patch updates the comments in qemu.conf, including a description of
this new behavior.

# The user for QEMU processes run by the system instance. It can be
# specified as a user name or as a user id. The qemu driver will try to
# parse this value first as a name and then, if the name doesn't exist,
# as a user id.

# Since a sequence of digits is a valid user name, a leading plus sign
# can be used to ensure that a user id will not be interpreted as a user
# name.
#
# Some examples of valid values are:
#
# user = "qemu" # A user named "qemu"
# user = "+0" # Super user (uid=0)
# user = "100" # A user named "100" or a user with uid=100

#user = "root"

# The group for QEMU processes run by the system instance. It can be
# specified in a similar way to user.
