e2fsprogs: modify ptest script

e2fsprog testsuite used to log results into its own log file into
/usr/lib/e2fsprogs/ptest/test.log. Therefore console output was not available and
redirecting ptest-runner output into a log file would not capture output of any
individual tests. So overall the whole e2fsprogs testsuite consisting of about
300 tests was evaluated as a single test.

This patch ensures the e2fsprogs test_script output is not automatically redirected
while executing during run-ptest. Any redirection is up to the user.
Additionally, the results of tests are prefixed by more canonical "PASS:" FAIL:"
based on the actual test results.

Aditionally, remove various files created by the testsuite.
