LsVarLog parser does not handle group name containing space

[rahulXs]

LsVarLog parser is returning ValueError while parsing lines containing group name with space.

# Example 1
-rw-r--r--.  1 root   domain users@CR.LOCAL        36548 Jan 13 10:43 Xorg.1.log
-rw-r--r--.  1 root   domain users@CR.LOCAL        28245 Jan 13 10:38 Xorg.1.log.old
# Example 2
-rw-r--r--.  1 root   domain users        40893 Jan 31 16:34 Xorg.1.log
-rw-r--r--.  1 root   domain users        36911 Dec 20 09:49 Xorg.1.log.old
