Remove export static DH ciphersuites

Browse source 
Remove support for the two export grade static DH ciphersuites. These two
ciphersuites were newly added (along with a number of other static DH
ciphersuites) to 1.0.2. However the two export ones have *never* worked
since they were introduced. It seems strange in any case to be adding new
export ciphersuites, and given "logjam" it also does not seem correct to
fix them.

Changes between 1.0.2a and 1.0.2b [xx XXX xxxx]
*) Removed support for the two export grade static DH ciphersuites
EXP-DH-RSA-DES-CBC-SHA and EXP-DH-DSS-DES-CBC-SHA. These two ciphersuites
were newly added (along with a number of other static DH ciphersuites) to
1.0.2. However the two export ones have *never* worked since they were
introduced. It seems strange in any case to be adding new export
ciphersuites, and given "logjam" it also does not seem correct to fix them.
[Matt Caswell]
*) Only support 256-bit or stronger elliptic curves with the
'ecdh_auto' setting (server) or by default (client). Of supported
curves, prefer P-256 (both).
