[Buildroot] [git commit] sysv init scripts: use symbolic names in trap command

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=286e4d94344f04c80cc4f3158bc0a14b80301638
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Not really necessary(*), but checkbashisms complains about
"trap with signal numbers".

(*) Quoting man 1p trap:
   trap [action condition...]
   [...]
   The condition can be EXIT, 0 (equivalent to EXIT),
   or a signal specified using a symbolic name, without the SIG prefix
   [...]
   XSI-conformant systems also allow numeric signal numbers[...]

Only one file is affected by this commit, and it should be checked
whether it really needs to ignore SIGTERM/SIGHUP or if the trap commands
can simply be removed:
