SOCKET_PATH_HOME is to specify environment variable "HOME",
so it should not contain "/pdump_sockets"  in the macro.
So remove "/pdump_sockets" from SOCKET_PATH_HOME
and create new macro for "/pdump_sockets". Similary removed
"/pdump_sockets" from SOCKET_PATH_VAR_RUN.
Changes are done in pdump_get_socket_path() to accommodate
new socket path changes.

Fixes: 278f945402c5 ("pdump: add new library for packet capture")

I think the default socket directory should contain dpdk as prefix.
Like dpdk-pdump-sockets (I think dash is preferred for filenames).
I wonder whether it should be a hidden directory:
	~/.dpdk-pdump-sockets
And after all, why not simply
	~/.dpdk/
It would allow other DPDK applications to put some files.

Hmm I would keep the name dpdk-pdump-sockets as library creates this only for pdump sockets.
Hidden directory just gives the advantage of not cluttering the display. If your comment is for the same I can add a . in the directory name:-).
