Subject: src: account for OpenSSL unexpected version

Fixes a crash that occurs because the logic to parse for an OpenSSL
version didn't account for OpenSSL_version returning a value that
doesn't match the expected pattern of OpenSSL 1.1.0i 14 Aug 2018.
In Electron's case, OpenSSL_version returns just BoringSSL, which in
combination with the search logic not accounting for the delimiter not
being present caused an out-of-bounds crash:

out_of_range was thrown in -fno-exceptions mode with message "basic_string"

This fixes that by checking for the null terminator and returning 0.0.0
when the target delimiter isn't present.
