There is a test to check that 'genrsa' doesn't accept absurdly low
number of bits. Apart from that, this test is designed to check the
working functionality of 'openssl genrsa', so instead of having a hard
coded lower limit on the size key, let's figure out what it is.

(cherry picked from commit ec46830f8a)
As per documentation, the RSA keys should not be smaller than 64bit (the
documentation mentions something about a quirk in the prime generation
algorithm). I am adding check into the code which used to be 16 for some
reason.
My primary motivation is to get rid of the last sentence in the
documentation which suggest that typical keys have 1024 bits (instead
updating it to the now default 2048).
I *assume* that keys less than the 2048 bits (say 512) are used for
education purposes.
The 512 bits as the minimum have been suggested by Bernd Edlinger.
