Increase EFI file alignment

Although file alignment for EFI apps is not clear, most of the UEFI
accept defaulf file alignment (0x200). Nevertheless some of the UEFI
bootloaders require file alignment to be 0x1000 (e.g. Lenovo Miix 630,
Lenovo Yoga C630, etc). Increase file alignment to the desired value.

Fixes #670
