build(tools): avoid unnecessary link

In their respective makefiles, cert_create, encrypt_fw and fiptool
depend on the --openssl phony target as a prerequisite. This forces
those tools to be re-linked each time.

Move the dependencies on the --openssl target from the tools to their
makefiles all targets, to avoid unnecessary linking while preserving the
OpenSSL version printing done in the --openssl targets when in debug.
