[LTP] [PATCH v2] nfs: Adapt the lib to allow to test in 2-host mode

[Petr Vorel]

Hi Sebastian,

> nfs_lib.sh checked key server_side prerequisites on the system under test.
> In 2_host setup this incorrectly required server_side tools on lhost.

> Switch exportfs and rpc.mountd/rpc.statd checks in nfs_setup() to
> tst_rhost_run(). This aligns netns and 2-host handling in one path and
> keeps 2-host checks on rhost.

Thanks, merged!

Kind regards,
Petr
