[ Upstream commit 647b8dd5184665432cc8a2b5bca46a201f690c37 ]

PACKET_TX_TIMESTAMP is defined in if_packet.h but it is not included in
test. Include it instead of <netpacket/packet.h> otherwise the error of
redefinition arrives.
Also fix the compiler warning about ambiguous control flow by adding
explicit braces.

Fixes: 8fe2f761cae9 ("net-timestamp: expand documentation")
