axfer: test: use memfd_create() for mapper-test

Browse source 
The mapper test program writes audio data frame to files, and read
them from the files, then validate them. For the operations, usage of
any in-memory file is good to shorten time of overall operations.

This commit uses shm by memfd_create().
