Fixes: #244
SO_RESUEPORT was introduced in Linux 3.9 and later.
This change allows NCCL to compile against older releases.
The functionality is only required if the user is specifying
a NCCL bootstrap address via an environment variable.
[ROCm/rccl commit: 7f2b337e70]
Two minor issues are solved:
+ Enclose the kernel function with parenthesis as hip-clang defines
`hipLaunchKernelGGL` as macro.
+ Need to explicitly include <hsa.h> for hip-clang.
[ROCm/rccl commit: 41310144f6]
Perform exact matching when the prefix "=" is specified in the NCCL_IB_HCA variable to exclude HCAs mlx5_X[0-9]+ when mlx5_X is specified.

Current SHM object name would only use pidHash and ranks as
identification, which would collide each other when program runs with
multiple communicators. Here we added commId info into pidHash, it makes
'pidHash'es of different communicators keeping in same process will be
distincted with each other.
