all_test.go - remove the temp db between scripts to prevent not quite closed/deleted/race.

malloc5.test - skip tests requiring memstats collection
pager1.test - skip 2 tests in non-functional sets.
snapshot_fault.test - skip test w/failing forcedelete
testdata/tcl/tester.tcl - fix get_pwd to return output of 'cd'
