openssl: sanity check that the bignum module is present

Browse Source 
The crypto_use_bigint_in_x86-64_perl patch uses the "bigint" module to
transparently support 64-bit integers on 32-bit hosts.  Whilst bigint (part of
bignum) is a core Perl module not all distributions install it (notable Fedora
23).

As the error message when bignum isn't installed is obscure, add a task to check
that it is available and alert the user if it isn't.
