arm/fiptool: fix native linkage

The Makefiles in TF-A have changed since this recipe was last altered,
and our BUILD_LDFLAGS are no longer being respected. This means the built
objects don't have the correct RPATH, so they fail to run if the host
doesn't have libcrypto.so.4 (from OpenSSL 4) installed.

Pass all of our BUILD_* flags via HOSTCC*, and delete the now redundant
sed operations.
