Fix off-by-one error in ada_fold_name
I'm seeing a libstdc++ assertion failure when running GDB's "maint selftest"
command when GDB is configured with the following CFLAGS and CXXFLAGS as
part of the configure line:
CFLAGS='-D_GLIBCXX_DEBUG -g3 -O0' CXXFLAGS='-D_GLIBCXX_DEBUG -g3 -O0'
This is what I see when running the self tests:
(gdb) maint selftest
Running selftest aarch64-analyze-prologue.
Running selftest aarch64-process-record.
Running selftest arm-record.
Running selftest arm_analyze_prologue.
Running selftest array_view.
Running selftest child_path.
Running selftest cli_utils.
Running selftest command_structure_invariants.
Running selftest copy_bitwise.
Running selftest copy_integer_to_size.
Running selftest cp_remove_params.
Running selftest cp_symbol_name_matches.
Running selftest dw2_expand_symtabs_matching.

$1 = 8
(top-gdb) p name.size()
$2 = 8
My patch adjusts the comparison to only copy name.size() characters
from the string. I've added a separate statement for NUL character
termination of fold_buffer[].
