Deflaky ObsoleteFilesTest (#9049)

Summary:
WaitForFlushMemTable() may only wait for mem flush but not background flush
finishing. The the obsoleted file may not be purged yet.
fcaa7ff638/db/db_impl/db_impl_compaction_flush.cc (L2200-L2203)

Use WaitForCompact() instead to wait for background flush job.
