Cygwin: fhandler_netdrive: fix character conversion required for NFS shares

While filenames on NFS shares are converted internally to a widechar
representation of the input bytes treated as the default system ANSI
codepage (CP_ACP), this doesn't hold for share names.  The names
returned by WNetEnumResourceW are just the original bytes dropped
verbatim into WCHAR.

The original conversion from 7db1c6fc4e2a ("Cygwin: //server: revert
to using WNet and support NFS shares") was erroneous in that it
treated the bytes as ISO-8859-1, not as CP_ACP codepoints.

Fix the conversion to convert from CP_ACP to widechar.  Use a tmp_pathbuf
buffer for the new widechar string instead of malloc/free.  Extend the
comment, better explaining the encoding difference between files and
shares.
