net-mgmt/tcpreplay: Remove libpcapnav from build dependencies

The pcapnav is unused in this program - the binaries with or without it
doesn't differ. The ldd says isn't linked to libpcapnav.
Details: the src/common/fakepcapnav.h includes pcapnav.h if it exists
(HAVE_PCAPNAV). If it doesn't exist it fakepcapnav.h defines some
structure (they are same in libpcapnav's pcapnav.h).
The tcpreplay doesn't use libpcpnav's library. Tcpreplay (re)defines
them - the function doesn't nothing as the comment in
src/common/fakepcapnav.c says.
Remove program-transform-name option too.
