[Patch, testsuite] Skip some more tests for targets with int size < 32

[Senthil Kumar Selvaraj]

Hi,

  This patch requires int32plus support for a few more tests - these
  were failing for the avr target.

  bswap-2.c uses left shifts wider than 16 bits on a char, and
  pr68067-{1,2} use an out of range negative number (INT_MIN for 32 bit int).

  If this is ok, could someone commit please? I don't have commit access.

Regards
Senthil
