lib/crypto: x86/sha1-ni: Convert to use rounds macros

The assembly code that does all 80 rounds of SHA-1 is highly repetitive.
Replace it with 20 expansions of a macro that does 4 rounds, using the
macro arguments and .if directives to handle the slight variations
between rounds.  This reduces the length of sha1-ni-asm.S by 129 lines
while still producing the exact same object file.  This mirrors
sha256-ni-asm.S which uses this same strategy.
