Fix for a test failure on Solaris/x86/gcc introduced by the patch for bug #27483.

Removed values with more than 15 significant digits from the test case. Results of 
reading/printing such values using system library functions depend on implementation 
and thus are not portable.

mysql-test/r/type_float.result:
  Removed values with more than 15 significant digits from the test case.
mysql-test/t/type_float.test:
  Removed values with more than 15 significant digits from the test case.
