MFH: r476826 sysutils/dvd+rw-tools: Fix issue appending more than 25gb on BD-R DL discs

While burning ISO Multisession BD-R 50G growisofs reports no space left while
24G+ are available.

Backport a fix from Debian [1] to address the issue.

While I'm here, document description and origins of both patches [1][2] that
apply to same source file, for our future selves, and to avoid confusion
as both chunks reference the same variable.
