Modified Files:
        src/sys/external/bsd/gnu-efi/dist/lib: sread.c

Log Message:
The device path passed to EFI_BOOT_SERVICES.LocateDevicePath() may be
modified and the resulting device path may not be aligned in such a way
that the PathName string is not 16-bit aligned.

Fix OpenSimpleFileRead to make a copy of the device path to ensure
alignment before attempting to open a file. Idea from Tianocore's EFI
shell Library/FileIO.c LibOpenFile().
