buildtools: fix build with busybox

If using busybox for mktemp and awk (as in Alpine),
some bugs prevent the script from running:

1/ It seems busybox mktemp requires the pattern to have at least
6 X and no other suffix.
The same has been fixed for other scripts in the past:
commit 3771edc35438 ("buildtools: fix build for some mktemp")

2/ It seems busybox awk does not accept the regex ^.*{
except if the opening curly brace is escaped.

Fixes: 4c82473412e8 ("build: add internal tag check")
Fixes: 68b1f1cda5b4 ("build: check AVX512 rather than binutils version")
Fixes: 3290ac14eb94 ("buildtools: detect discrepancies for experimental symbols")
