patch 9.2.0475: runtime(netrw): bookmark paths not normalized

patch 9.2.0475: runtime(netrw): bookmark paths not normalized

Problem: the bookmarks list can have duplicate entries, more often
in win32 (due to mixed slashes and capitalization) and when
g:netrw_keepdir=0 (which could introduce relative paths).
Duplicate entries could be: C:oo\BAR az.file
c:oo ar az.file
c:/foo\BAR/baz.file
BAR/baz.file
Solution: Normalize the paths and make sure they are always absolute
(J. Paulo Seibt).
