[Buildroot] [PATCH] bash: disable bash malloc by default

[Daniel Sabogal <dsabogalcc@gmail.com>]

Bash's malloc relies on sbrk which is implemented as
a fail-only stub in musl. Presently, it is disabled
when configured for static libs. Instead, default to
using libc malloc.

Fixes:
# bash
bash: xmalloc: locale.c:81: cannot allocate 18 bytes (0 bytes allocated)
