[PATCH container] esxi plugin: keep uuid inside vm the same as in esxi

[Nicolas Reinecke <nr@das-labor.org>]

There needs to be done some byte swapping in the first 3 parts to keep
the uuid the same.

RegEx Group Mapping to Bytes:
$1-$4 : 1st section (4 bytes) -> Reversed to $4$3$2$1
$5-$6 : 2nd section (2 bytes) -> Reversed to $6$5
$7-$8 : 3rd section (2 bytes) -> Reversed to $8$7
$9    : 4th section (2 bytes) -> Kept as-is
$10   : 5th section (6 bytes) -> Kept as-is
