Tests: unbreak ssl_password_file.t with upcoming OpenSSL 1.0.2.
The 512-bit keys, as generated by default by "openssl genrsa" in older
versions, are rejected by OpenSSL library built from master branch (and
upcoming OpenSSL 1.0.2). This brokes the test if the "openssl" binary
is old (e.g., system one), but nginx is compiled against new OpenSSL.
Fix is to explicitly generate 2048 bit keys. This is also consistent to
what we generate in other places.
