[PATCH nfs-utils] start-statd: Fix shellcheck warnings

[Salvatore Bonaccorso <carnil@debian.org>]

From: Ben Hutchings <benh@debian.org>

shellcheck currently complains:

In utils/statd/start-statd line 14:
       [ 1`cat /run/rpc.statd.pid` -gt 1 ] &&
          ^----------------------^ SC2046 (warning): Quote this to prevent word splitting.
          ^----------------------^ SC2006 (style): Use $(...) notation instead of legacy backticks `...`.

Did you mean:
       [ 1$(cat /run/rpc.statd.pid) -gt 1 ] &&

In utils/statd/start-statd line 15:
       kill -0 `cat /run/rpc.statd.pid` > /dev/null 2>&1
               ^----------------------^ SC2046 (warning): Quote this to prevent word splitting.
               ^----------------------^ SC2006 (style): Use $(...) notation instead of legacy backticks `...`.

Did you mean:
       kill -0 $(cat /run/rpc.statd.pid) > /dev/null 2>&1

Use quotes and $() as recommended.
