[LTP] [PATCH 1/1] tst_net.sh: Remove -B option from tst_rhost_run()

[Petr Vorel]

This option was added in 6bcf7ce05 ("lib: tst_rhost_run: new option -B
for saving background log") and used in tst_dump_rhost_cmd() added in
921fb2d2c ("network/tst_netload: dump background netstress output on
failure").
But d6ce33a2e ("netstress: set port dynamically on the server-side")
moved logging into netstress.log, created by netstress.c, -B is not
used any more.

NOTE: if this feature is reintroduced, it should check whether
TST_NEEDS_TMPDIR=1 is set (similar to fix e3a1aa106 ("net/tst_netload:
TBROK when TST_NEEDS_TMPDIR not set")).
