fcgi.writePairs() writes key length twice rather than key length then value length

[trotterdylan]

The fcgi package has an error in the writePairs() function. On lines 174-175 It writes
the key length twice instead of writing the key length and then the value length:

  n := encodeSize(b, uint32(len(k)))
  n += encodeSize(b[n:], uint32(len(k)))

Should read:

  n := encodeSize(b, uint32(len(k)))
  n += encodeSize(b[n:], uint32(len(v)))
