app/testpmd: restore ixgbe bypass commands

[ upstream commit 8d1bd1c ]

Since the switch to meson, ixgbe bypass commands were ineffective as the
RTE_LIBRTE_IXGBE_BYPASS build flag was not set, even though the
net/ixgbe driver had this feature compiled in.

Fixes: 16ade73 ("app/testpmd: build with meson")
