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
