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

[Fabrice Fontaine]

Use nls option to enable/disable NLS depending on BR2_SYSTEM_ENABLE_NLS
(and fix second patch) to avoid a build failure if libintl.h is found
but xgettext is not available:

Has header "libintl.h" : YES
Library intl found: NO

po/meson.build:28:5: ERROR: Can not do gettext because xgettext is not installed.

Fixes:
