SIZE_RE regex is incorrect for returned string

[Andrew Kerr]

imageutils.py line 32 has an incorrect regex:

SIZE_RE = re.compile(r"(\d+)(\w+)?(\s*\(\s*(\d+)\s+bytes\s*\))?", re.I)

This will not properly parse the result of 'qemu-img info' line:

virtual size: 2.0G (2147483648 bytes)

This results in the returned size of the image not being in Bytes. The correct regex should be:

SIZE_RE = re.compile(r"(\d+\.?\d*)(\w+)?(\s*\(\s*(\d+)\s+bytes\s*\))?", re.I)
