ShellPkg: Fix bad TimeZone (TZ) conversion.

EFI_UNSPECIFIED_TIMEZONE means display local time. TZ of 0 is UTC.
Thus EFI_UNSPECIFIED_TIMEZONE means ignore TZ, 0 means UTC. When this code is
fixed to adust file TZ to local TZ you need to preserve
EFI_UNSPECIFIED_TIMEZONE.

FAT always return EFI_UNSPECIFIED_TIMEZONE.
Modern filesystems, HFS+, NTFS, ext3, etc store time in UTC.
