crypto: arc4 - improve performance by adding ecb(arc4)

Currently arc4.c provides simple one-byte blocksize cipher which is wrapped
by ecb() module, giving function call overhead on every encrypted byte. This
patch adds ecb(arc4) directly into arc4.c for higher performance.

Intel Core 2, x86-64  : x1.9
Intel Atom N260, i386 : x1.4
