librdmacm/libibverbs: Add bnxtre RDMA provider to OFED build infrastructure

Browse source 
Extend the FreeBSD OFED build framework to include the Broadcom bnxtre RDMA
provider library.

This change:

 -Registers libbnxtre in src.libnames.mk so it is built and installed as part
  of the OFED libraries.
 -Adds bnxtre to the OFED pcap dependency set when MK_OFED is enabled.
 -Declares proper dependency mappings for bnxtre (ibverbs, pthread).
 -Introduces LIBBNXTREDIR for consistent object directory handling.
 -Updates libibverbs and librdmacm build rules to link against libbnxtre,
  enabling Broadcom RoCE device support at runtime.
 -libbnxtre library uses below constructor to register with the libibverbs,
  static attribute((constructor)) void bnxt_re_register_driver(void)

These updates ensure that applications using libibverbs and librdmacm can
discover and use Broadcom bnxt RDMA devices on FreeBSD.
