bytes: vary the input alignment to Compare argument in compare_test.go
Currently there are no tests that vary the alignment of Compare arguments.
Since Compare is written in assembly on most platforms (in internal/bytealg)
we should be testing different input alignments. This change modifies TestCompare
to vary the alignment of the second argument of Compare.
Updates #26129
