Thomas Monjalon 21a7f4e264 app/test: fix build without librte_cmdline 
Some features are not available if LIBRTE_CMDLINE is disabled:
- interactive commands
- cmdline tests
Remove also cmdline_parse includes which are not needed.

* MBUF
* ====

* #. Allocate a mbuf pool.
*
* - The pool contains NB_MBUF elements, where each mbuf is MBUF_SIZE
* bytes long.
*
* #. Test multiple allocations of mbufs from this pool.
*
* - Allocate NB_MBUF and store pointers in a table.
* - If an allocation fails, return an error.
* - Free all these mbufs.
* - Repeat the same test to check that mbufs were freed correctly.
*
* #. Test data manipulation in pktmbuf.
*
* - Alloc an mbuf.
* - Append data using rte_pktmbuf_append().
* - Test for error in rte_pktmbuf_append() when len is too large.
* - Trim data at the end of mbuf using rte_pktmbuf_trim().
* - Test for error in rte_pktmbuf_trim() when len is too large.
* - Prepend a header using rte_pktmbuf_prepend().
* - Test for error in rte_pktmbuf_prepend() when len is too large.
* - Remove data at the beginning of mbuf using rte_pktmbuf_adj().
* - Test for error in rte_pktmbuf_adj() when len is too large.
* - Check that appended data is not corrupt.
* - Free the mbuf.
* - Between all these tests, check data_len and pkt_len, and
* that the mbuf is contiguous.
* - Repeat the test to check that allocation operations
* reinitialize the mbuf correctly.
