kernel version parsing panic

[zz85]

a kernel version name like 4.9.266-0.1.ac.225.84.332.metal1.x86_64 causes procfs to panic here

procfs/src/sys/kernel/mod.rs

Line 66 in d8f16dd

let patch = patch.parse().map_err(|_| "Failed to parse patch version")?;

one fix is to default to 0 values, another would be to parse the first readable number

pub patch: u8 also mean that numbers > 255 wouldn't fit

Hi @zz85 and @fabricedesre. Sorry this took so long, but this fix is now released as 0.10.0.
