t/lib-httpd: increase ssl key size to 2048 bits

Recent versions of openssl will refuse to work with 1024-bit RSA keys,
as they are considered insecure. I didn't track down the exact version
in which the defaults were tightened, but the Debian-package openssl 3.0
on my system yields:

  $ LIB_HTTPD_SSL=1 ./t5551-http-fetch-smart.sh -v -i
  [...]
  SSL Library Error: error:0A00018F:SSL routines::ee key too small
  1..0 # SKIP web server setup failed

This could probably be overcome with configuration, but that's likely
to be a headache (especially if it requires touching /etc/openssl).
Let's just pick a key size that's less outrageously out of date.
