[vfs] CFile: remove 'virtual' from destructor

[pvr] Fix missing recordings

This fixes an issue with missing recordings that occurs under following
circumstances:

- Recording A in subdirectory "TV Show XY"
- Recording B in subdirectory "TV show xy"

Because of the difference in case, recording B won't show up in any
sub folder. This can happen due to EPG inconsistencies.

The presented sub folders are created with case-insensitive matching
using CFileItemList::Contains in GetSubDirectories.
But when determining if a recording belongs into a directory, the
comparison is case-sensitive (in IsDirectoryMember).

This commit changes the IsDirecroryMember check to be case-insensitive.

Revert "[nfs] - better fix for fe97d68f87d6985b2bf57d8e942b36b5e7373066 - possibly fixes #14727 - thx jm for the idea :)"

This reverts commit dd4dd2e91bc083a23fe7b46ae4c291c6672d32e0.

This commit created issues comparing paths when the export and the path was the same and did not contain a trailing slash, in addition, it removed the correct reversal of ordering of m_exportList generated by GetExportList.

    [nfs] replacement fix for dd4dd2e91bc083a23fe7b46ae4c291c6672d32e0 (issue #14727).

    If the exportPath is the same as the path is then bypass the substr methods, and return the correct relativePath.
