[SHELL] Fix klibc DEBUG compilation
dash didn't compile in DEBUG mode against klibc for all long time.
Now it only fails at link stage for not having setlinebuf(3) and
freopen(3).

Fixes:

usr/dash/show.o: In function `opentrace':
show.c:(.text+0x36): undefined reference to `freopen'
show.c:(.text+0x86): undefined reference to `setlinebuf'

Skip setlinebuf and use fclose/fopen inside __KLIBC__
Compile tested with debug in klibc and against glibc in dash repo.
