In a large number of patches, remove unneeded '..' in paths.

In a large number of patches, remove unneeded '..' in paths.

In most cases we had both ../foopkg/foopkg as the first path and
this simply became foopkg (the second path was already correct for
the default strip level which is why the patch applies normally).

In a few cases the second path was '.' which is valid but not as
clear as 'b' (which is what git shows for example) so update
that while we're at it.
