[bug#27754] [PATCH] vm: Increase disk size overhead estimate.

* gnu/build/vm.scm (estimated-partition-size): Add 25% to the graph size.

Guix,

Add a conservative 5% to the disk size overhead estimate. It's enough to
make ‘guix system disk-image gnu/system/install.scm’ work again for me.

Kind regards,

On second thought, since this is such a clear-cut fix, I'm going to be
bold and just push it. Sorry for the noise.

Kind regards,
