libtirpc: Disable DES functions on uclibc

uclibc does not provide these functions so dont expect them

/usr/lib/libtirpc.so: undefined reference to `key_encryptsession_pk'
/usr/lib/libtirpc.so: undefined reference to `getnetname'
/usr/lib/libtirpc.so: undefined reference to `cbc_crypt'
/usr/lib/libtirpc.so: undefined reference to `ecb_crypt'
/usr/lib/libtirpc.so: undefined reference to `getpublickey'
/usr/lib/libtirpc.so: undefined reference to `key_gendes'
