git: Set PKG_FORTIFY_SOURCE to 0 when lto enabled

If PKG_FORTIFY_SOURCE is not 0 and lto is enabled for package git, it
will fail to compile with the following example error:

/openwrt/staging_dir/toolchain-aarch64_generic_gcc-14.1.0_musl/include/stdio.h: In function 'process_curl_messages': /openwrt/staging_dir/toolchain-aarch64_generic_gcc-14.1.0_musl/include/stdio.h:90:8: error: inlining failed in call to 'always_inline' 'fwrite': function body can be overwritten at link time
   90 | size_t fwrite(const void *__restrict, size_t, size_t, FILE *__restrict);
      |        ^
http.c:355:33: note: called from here
  355 |                                 fprintf(stderr, "Received DONE message for unknown request!\n");
      |                                 ^

A related issue is #13016 .
This commit set PKG_FORTIFY_SOURCE to 0 if CONFIG_USE_LTO is y.

Close #24366
