Message:

Unify firmware search logic for arm64 and sun4v

Update tools/ew.py to first search for firmware binaries by checking an
environment variable, EW_QEMU_EFI_AARCH64 for arm64 and
OPENSPARC_BINARIES for sun4v. If this fails then try finding the
binaries in their expected default locations. If this also fails then
report an error on stderr and exit.
