Make mbedtls_ssl_get_bytes_avail tests more independent

Browse source 
Don't depend on the default sizes in the test programs: pass explicit
request and buffer sizes.

Don't depend on MAX_CONTENT_LEN (other than it not being extremely small:
this commit assumes that it will never be less than 101).
