innobackupex should remove stale xtrabackup_suspended file on start

In innobackupex init, added test for existance of suspend file, then report and attempt to remove if the file exists.

Created new test case bug1007466.sh that creates a fake suspend file before launching innobackupex and tests for warning in output file.
