```
std.os: Add DeviceBusy as a possible write error

In Linux when writing to various files in the virtual file system,
for example /sys/fs/cgroup, if you write an invalid value to a file
you'll get errno 16.

This change allows for these specific cases to be caught instead of
being lumped together in UnexpectedError.
