Bug#46448 trailing spaces are not ignored when user collation maps space != 0x20

Browse source 
In MySQL when the mapping for space is changed to something other than
0x20 by defining a different collation, then space is not ignored when
comparing two strings.

This was happening because the function that performs the comparison
of two strings while ignoring ending spaces, was comparing the collation
value of a space with the ascii value of the ' ' character. This should
be changed to do comparison between the collated values.

  Added test case to ensure trailing spaces are not ignored.
strings/ctype-simple.c:
  Bug#46448 trailing spaces are not ignored when user collation maps space != 0x20
  
  change my_strnncollsp_simple to compare collated values when checking
  for trailing spaces. Currently the comparison happens between a collated
  value and the ascii value.
