libstdc++: Remove dg-options "-std=gnu++20" from 21_strings tests
The testsuite will automatically select C++20 for these tests now, and
removing the hardcoded -std option allows them to be tested for C++23
and C++26 as well.
libstdc++-v3/ChangeLog:
* testsuite/21_strings/basic_string/cons/char/105995.cc: Remove
dg-options -std=gnu++20.
