[Buildroot] [PATCH v2 1/3] package/ca-certificates: don't hash certificates.crt

[Martin Bark <martin@barkynet.com>]

Currently c_rehash mistakenly hashes the certificates bundle
certificates.crt resulting in ${TAGET_DIR}/etc/ssl/certs/128805a3.0
incorrectly linking to ca-certificates.crt when it should be linked to
EE_Certification_Centre_Root_CA_2.pem

To fix this install certificates.crt to /etc/ssl/certs after we run
c_rehash to prevent it getting hashed by mistake.

Note: $(TARGET_DIR)/etc/ssl/certs/ is already removed during install so
this fix also works for rebuilds.
