[PATCH:xbacklight] Use double instead of int for value

[Nils Schneider]

Modern displays allow for fine grained brightness settings. For example,
my laptop allows for 852 brightness steps. In some situations I find it
useful to set the brightness below 1 percent (the minimum possible when
using integers).

This patch makes xbacklight use a double instead so lower brightness
values like 0.12 are possible.
