Search VTEFI directory for UEFI boot files.

When user install for example Windows in the reserved space of Ventoy USB stick in UEFI mode.
Windows will create part 3 as the EFI partition and when you boot the USB stick, the BIOS may skip Ventoy and directly boot the Windows.
To avoid this, we suggest to rename the directory name from EFI to VTEFI.
