[Buildroot] [PATCH 1/1] package/iputils: fix build without NLS

[Fabrice Fontaine]

Set USE_GETTEXT depending on BR2_SYSTEM_ENABLE_NLS as otherwise build
will fail if gettext is not installed on host because USE_GETTEXT is
enabled by default since version 20190324 and
https://github.com/iputils/iputils/commit/2615a527209bb408b54028ef6405075cadd4541b

Fixes:
