package/parted: disable on uclibc

Like postgreSQL (and imagemagick), parted does not build against uClibc
with locales enabled, due to an uClibc bug, see
http://lists.uclibc.org/pipermail/uclibc/2014-April/048326.html:

In file included from atari.c:42:
atari.c: In function 'atr_part_correct':
atari.c:221:9: error: dereferencing pointer to incomplete type 'struct __uclibc_locale_struct'
  return isalnum_l(part->id[0], atr_c_locale)
         ^~~~~~~~~

So disable parted on uclibc
