run_xfstests.sh: activate more tests that now work

I've gone through the set of xfstests that were previously found to
not work.  Some of those now do work, and with the addition of an
option to pass to "mkfs.xfs" a large number of other tests now
produce expected output as well.

This patch updates the default list of tests to run to reflect
the result of this exercise.  The following 50 additional tests
are now run by default:

    029 074 078 084-087 100 105 117 121 124 126 129-134
    164 165 167 174 181 184 186 187 192 214-216 227 236
    237 241 243 245-249 257-259 261 277 278 280 285 286

Test 127 completed without error, but it took from 1-3 hours so I
kept that out of the list.
