Stop calling evdns_set_random_bytes_fn()

Browse Source 
This function has been a no-op since Libevent 2.0.4-alpha, when
libevent got an arc4random() implementation.  Libevent has finally
removed it, which will break our compilation unless we stop calling
it.  (This is currently breaking compilation in OSS-fuzz.)

Closes #40371.

o Minor bugfixes (compatibility):
- Fix compatibility with the most recent Libevent versions, which
no longer have an evdns_set_random_bytes() function. Because
this function has been a no-op since Libevent 2.0.4-alpha,
it is safe for us to just stop calling it. Fixes bug 40371;
bugfix on 0.2.1.7-alpha.
