gdb/nat/linux-osdata.c: fix build on gcc-12 (string overfow)
On gcc-12 build fails as:
../../gdbserver/../gdb/nat/linux-osdata.c: In function 'void linux_xfer_osdata_processes(buffer*)':
../../gdbserver/../gdb/nat/linux-osdata.c:330:39: error:
'__builtin___sprintf_chk' may write a terminating nul past the end of the destination [-Werror=format-overflow=]
330 | sprintf (core_str, "%d", i);
| ^
It's an off-by-one case in an infeasible scenario for negative
huge core count. The change switches to std::string for memory
handling.
Tested by running 'info os processes' and checking CPU cores column.
