intelvbttool: Added support for reading vbt from sysfs

VBT on intel systems is available via sysfs as
    /sys/kernel/debug/dri/0/i915_vbt
However the size of this file reads as 0 causing
intelvbttool to fail. This patch implements incremental reads
with realloc for such cases.
After this patch is applied, intelvbttool can be used as follows:
    sudo intelvbttool -f /sys/kernel/debug/dri/0/i915_vbt -d
