Modify vg_test wrapper to support PTEST formats

Change the valgrind regression test script vg_regtest to
support the yocto ptest stdout reporting format.  The commit adds
'--yocto-ptest' as an optional argument to vg_regtest, which alters
the output to use the ptest infrastructure reporting format:
    "[PASS|SKIP|FAIL]: testname"
instead of valgrind's internal test reporting format.  Without the added
option, --yocto-ptest, the valgrind regression test output is unchanged.

Enforce 30 seconds limit for the test.
This resume execution of the remaining tests when valgrind hangs.
