path/filepath: do not Clean("a/../c:/b") into c:\b on Windows
Do not permit Clean to convert a relative path into one starting
with a drive reference. This change causes Clean to insert a .
path element at the start of a path when the original path does not
start with a volume name, and the first path element would contain
a colon.
This may introduce a spurious but harmless . path element under
some circumstances. For example, Clean("a/../b:/../c") becomes `.\c`.
This reverts CL 401595, since the change here supersedes the one
in that CL.
