xentop 显示VM名字不全。Allow full domain name display with xentop

Add a '-f' option to xentop to allow the full domain name to be displayed. This
is the original behavior which can cause the display to be unaligned. Customers
have requested this because only the trailing characters of their domain names
are unique and therefore cannot be distinguished when the display is limited to
a 10 character width.
