add additional ReplaceAll in pathsep to cater for different pathsep (go-gitea#34061)

The doctor storage check reconstructs the lfs oid by producing a string
where the path separator is stripped
ab/dc/efg -> abdcefg. Windows however uses a backslash and thus the
ReplaceAll call doesn't produce the correct oid resulting in all lfs
objects being classed as orphaned.
This PR allows this to be more OS agnostic.

Closes go-gitea#34039
