tools/firmware/ihex2fw: Replace explicit alignment with ALIGN
(X + 3) & ~3 is the same as ALIGN(X, 4), so replace all of the
instances of the formwer in the code with the latter. While at it,
introduce a helper variable 'record_size' to avoid duplicating length
calculatin code. No functional change intended.
