[llvm-profdata] Make tests more readable (NFC)

These tests generally use one printf for each field of
RawInstrProf::ProfileData except the lines being touched in this
patch.  These lines print two fields, namely NumValueSites and
NumBitmapBytes, with one printf, which is very confusing.  (Note that
the 4-byte printf at the end of the group is padding to make the
struct size a multiple of 8 bytes.)

This patch makes the tests a litle more readable by splitting
NumValueSites and NumBitmapBytes into two separate lines.
