Achill Gilgenast 7837fb8e97 kallsyms: fix build without execinfo 
commit a95743b530 upstream.

Some libc's like musl libc don't provide execinfo.h since it's not part of
POSIX.  In order to fix compilation on musl, only include execinfo.h if
available (HAVE_BACKTRACE_SUPPORT)

This was discovered with c104c16073 ("Kunit to check the longest symbol
length") which starts to include linux/kallsyms.h with Alpine Linux'
configs.
