Reported by sirgazil &lt;sirgazil@zoho.com&gt;.

Previously, leading zeros would be removed, leading to an "invalid"
UUID:

  (uuid-&gt;string (uuid "00CA-050E" 'fat32))
  ⇒ "CA-50E"
  (string-&gt;uuid "CA-50E" 'fat32)
  ⇒ #f

* gnu/system/uuid.scm (fat-uuid-&gt;string): Pad digits with zeros.
* tests/uuid.scm ("uuid, FAT32, leading zeros preserved"): New test.
