I noticed through the Guix Data Service that some narinfo files from
ci.guix.gnu.org have an excessive NarSize.

These are the three that I've found, but there could be more.


/gnu/store/qln574djfgl8h9glij9id8jips7nnrlw-flightgear-2018.3.5
NarSize: 18446744072099351584

/gnu/store/qhix6afvy2a6n7hlx4qgdns461p8kdnv-repeat-masker-4.1.1
NarSize: 18446744071612438544

/gnu/store/wd9z64xpck56xzf52jwlpg8vb610b0ym-repeat-masker-4.1.1
NarSize: 18446744071612438544


There's additional information on IRC: http://logs.guix.gnu.org/guix/2021-01-31.log#152751

Cc'ing Mathieu in case this is related to the new offloading mechanism.
