In bareudp.sh, this script uses /bin/sh and it will load another lib.sh
BASH script at the very beginning.
But on some operating systems like Ubuntu, /bin/sh is actually pointed to
DASH, thus it will try to run BASH commands with DASH and consequently
leads to syntax issues:
# ./bareudp.sh: 4: ./lib.sh: Bad substitution
# ./bareudp.sh: 5: ./lib.sh: source: not found
# ./bareudp.sh: 24: ./lib.sh: Syntax error: "(" unexpected
Fix this by explicitly using BASH for bareudp.sh. This fixes test
execution failures on systems where /bin/sh is not BASH.

Switch bareudp testing to use setup_ns, which sets up rp_filter by default.
This allows us to remove the manual rp_filter configuration from the script.
Additionally, since setup_ns handles namespace naming and cleanup, we no
longer need a separate cleanup function. We also move the trap setup earlier
in the script, before the test setup begins.

Test different encapsulation modes of the bareudp module:
* Unicast MPLS,
* IPv4 only,
* IPv4 in multiproto mode (that is, IPv4 and IPv6),
* IPv6.
Each mode is tested with both an IPv4 and an IPv6 underlay.
v2:
* Add build dependencies in config file (Willem de Bruijn).
* The MPLS test now uses its own IP addresses. This minimises
the amount of cleanup between tests and simplifies the script.
* Verify that iproute2 supports bareudp tunnels before running the
script (and other minor usability improvements).
