Remove OPENSSL_NO_STDIO guards around certain SSL cert/key functions

These functions are:

    SSL_CTX_use_certificate_file
    SSL_CTX_use_RSAPrivateKey_file

Add a coverage target

For simplicity, this currently only adds a single target in a
configuration that attempts to maximize coverage. The true CI coverage
from all the various builds may be a little larger.

The coverage run has the following configuration:
- no-asm: since we can't track asm coverage anyway, might as well measure the
  non-asm code coverage.
- Enable various disabled-by-default options:

Fix ubsan 'left shift of negative value -1' error in satsub64be()

Baroque, almost uncommented code triggers behaviour which is undefined
by the C standard. You might quite reasonably not care that the code was
broken on ones-complement machines, but if we support a ubsan build then
we need to at least pretend to care.

It looks like the special-case code for 64-bit big-endian is going to
behave differently (and wrongly) on wrap-around, because it treats the
values as signed. That seems wrong, and allows replay and other attacks.
