[WININET] Fix FtpFindFirtFile(A/W)

[Lionel Ulmer]

Ragnarok Online's updater sets lpszSearchFile to NULL to match all files in
the FTP server's directory which crashed when we tried to match the files
found using SLWAPI's PathMatchSpec function. Moreover, I also checked the
asynchronous code and it was buggy too (it tried to strdup a NULL string) so
I fixed it too.

                Lionel

Changelog:
  Fix the case where lpszSearchFile is NULL in FtpFindFirstFile
