mount: Correctly return context.Canceled for interrupted syscalls

Browse Source 
bazil/fuse expects us to return context.Canceled to signal that a
syscall was successfully interrupted. Returning a wrapped version of
that error however causes the fuse library to signal an EIO (input/output
error). Thus unwrap context.Canceled errors before returning them.

Bugfix: Improve handling of interrupted syscalls in `mount` command
Accessing restic's fuse mount could result in "input / output" errors when
using programs in which syscalls can be interrupted. This is for example the
case for go programs.
We have corrected the error handling for interrupted syscalls.
