Banner change + minor fix for curve detection

Browse Source 
In order to tell openssl binaries better apart the short banner below the
hash tag signs contain now also the date. That is the short version of the
build date unless it is not supplied which is the case of opensuse. Then
the name contains the date and it's taken from there.

The start and end banner lines have the same length now.

"sieve" was added in a comment and the sequence where sieve appears in
a pattern was trying to match other occurences (i.e. after nntp)

While testing the banners it appeared under Linux that a) the vendor
supplied openssl sometimes hangs during startup when determining the
supported curves using -connect b) a pattern was missing to detect
whether the curve was not supported which falsely labeled all supplied curves
as supported when using /usr/bin/openssl . The pattern for the latter
was added (b). For a) there needs to be a follow up PR to avoid the
long delays.
