Don't check pipe name for illegal characters

This patch:

1. modifies kernel32 pipe test to use ">" character in the file name, so the
case of special characters in the name will be checked.

2. modifies wine_nt_to_unix_file_name() in ntdll to not check pipes for special
characters since pipes aren't usual files.
