Tidy up systemCaCertificates() function in OpenSSL backend

Browse Source 
As pointed out by Marc Mutz in another review, the Android branches of
its #if-ery amounted to a complicated no-op, so simplify the #if-ery,
add a TODO and then simplify the code thereby freed of the need to
accommodate the #if-ery.

In the process, initialize a set of filenames with the two filenames
that we read certificates from after looping over the set, which might
have left those files being read twice.
