Commit 2523baf7fb4d ("qemu-keymap: Make references to allocations
static") made references to allocations static to ensure LeakSanitizer
can track them. This trick unfortunately did not work with gcc version
14.0.1; that compiler is clever enough to know that the value of the
"state" variable is only referred in the current execution of the
function and to put it on the stack.
Release references to allocations and suppress the error once for all.

LeakSanitizer complains about allocations whose references are held
only by automatic variables. It is possible to free them to suppress
the complaints, but it is a chore to make sure they are freed in all
exit paths so make them static instead.

We can return XKB_MOD_INVALID for AltGr which rightly gets flagged by
sanitisers as an overly wide shift attempt. Properly check the return
type and leave the bitmap as zero in that case. Tested output before
and after is unchanged with the gb and ara keymaps.

When compiling QEMU with "--enable-sanitizers --enable-xkbcommon --cc=clang"
there is a memory leak warning when running qemu-keymap:
$ ./qemu-keymap -f pc-bios/keymaps/de -l de
=================================================================
==610321==ERROR: LeakSanitizer: detected memory leaks
Direct leak of 136 byte(s) in 1 object(s) allocated from:
#0 0x5642830d0820 in __interceptor_calloc.part.11 asan_malloc_linux.cpp.o
#1 0x7f31873b8d2b in xkb_state_new (/lib64/libxkbcommon.so.0+0x1dd2b) (BuildId: dd32581e2248833243f3f646324ae9b98469f025)
SUMMARY: AddressSanitizer: 136 byte(s) leaked in 1 allocation(s).
It can be silenced by properly releasing the "state" again
after it has been used.

qemu-keymap generates qemu reverse keymaps from xkb keymaps,
which can be used with the qemu "-k" command line switch.
