locales fixes

[François Dumont]

Hi

     After having installed all necessary locales on my system I end up 
with 4 failures. Here is a patch to fix them all.

For numpunct test I consider that checking value of numpunct::grouping() 
result was not correct. libstdc++ doesn't control this value. I prefer 
to just check that values returned by numpunct are consistent with how 
numeric values are formatted.

For the others, regarding time_get, I found nothing really smart to do. 
For 4.cc I simply had to remove some characters not present anymore. And 
for 38081-1 and 38081-2, despite having glibc 2.19 it is still showing 
previous values on my system. I even wonder if it has anything to do 
with glibc version, it rather depends on the installed locale info, no ?

     * testsuite/22_locale/numpunct/members/char/3.cc: Check numpunct 
returned
     values are consistent with how numbers are formatted.
     * testsuite/22_locale/time_get/get_date/wchar_t/4.cc: Update expected
     values.
     * testsuite/22_locale/time_get/get_weekday/char/38081-1.cc: Don't 
use new
     values before glibc 2.20.
     * testsuite/22_locale/time_get/get_weekday/char/38081-2.cc: Likewise.

Tested under Linux x86_64.
