build: Add mbedtls to prep script

Patch it if patch files present in parent folder, ie:

- extlibs/mbedtls/ocf.patch (md5=96feff0a1627e465e05c350a47464cdf)
  (support for MBEDTLS_TLS_ECDH_ANON_WITH_AES_128_CBC_SHA256)

It is strongly recommended to rely on scons instead,
 if not possible, this can be done differently using this script.
