Switch from wolfssl to mbedtls as default

OpenWrt switched the default cryptographic library from wolfssl to mbedtls. This library is used for HTTPS/TLS in the Webserver providing LuCI and for the cryptographic operations in hostapd. mbedtls provides security updates in their LTS branch without changing the application binary interface (ABI) of the library. wolfssl provides a stable ABI only for a very limited subset of functions. mbedtls allows us to update only mbedtls without the need to recompile and upgrade all users of mbedtls.
