Remove unnecessary L suffixes on DES constants.

Browse Source 
Some of them were flagging -Wshorten-64-to-32 warnings. None of these
values are long, so just remove them. (I suspect this assumes unsigned
int is at least 32-bit, but we already assume this rather than wrap all
32-bit constants in UINT32_C(x).)

Ideally the c2l and l2c macros could be replaced with the load/store
functions but, like with the ciphers in decrepit, this is probably not
worth the effort for DES.
