Bug Description

[Impact]
hybrid-detect writes to /usr/share, which not be written to after package installation. hybrid-detect may fail to function properly if used on hybrid systems with read-only /usr partitions.

[Fix]
Write to /var/lib instead.

[Regression Potential]
Scope of possible regression is very limited; this only affects the hybrid-detect utility, which is only relevant on certain kinds of hybrid systems.

[Original Report]
When running debsums on my system I noticed the following entry:
debsums: changed file /usr/share/nvidia-common/last_gfx_boot (from nvidia-common package)

I tracked it down to hybrid-detect changing that file at runtime. This is definitely wrong as nothing should ever write to /usr after package installation. I'd suggest moving this to /var/lib instead.

I've installed this package on a precise-proposed/nouveau (non-hybrid) system, installed nvidia-173 through jockey, and confirm the fix has taken effect, with the file now existing in /var/lib. Running hybrid-detect on this system does not crash, and produces correct output.
