1140950d7b scanner: Use context only for cancellation
When the scanner is slower than the actual backup, the tomb cancels the
context passed to Scan(), which then returns ctx.Err(). In the end, the
main function prints an error message that is not helpful ("Context
cancelled") and exits with an error code although no error occurred.

The code now ignores the error in the context and just uses it for
cancellation. The scanner is not supposed to return an error anyway.

Closes #1978

b07bb3d8c3 Reject files excluded by name before calling lstat to improve scan speed
Adds a SelectByName method to the archive and scanner which only require
the filename as input, and can thus be run before calling lstat on the
file. Can speed up scanning significantly if a lot of filename excludes
are used.

c44e808aa5 backup: Fix deadlock
When the archiver is faster than the scanner, restic deadlocks. This
commit adds a `finished` channel to the struct in `ui/backup.go` so that
scanner results are ignored when the archiver is already finished.

Closes #1834
