  1. teddy: always initialize variable 

    Hyperscan fails to build with Clang when the "sometimes-unitialized"
check is switched on:

src/fdr/teddy_runtime_common.h:359:13: error: variable 'val' is used
uninitialized whenever 'if' condition is false
[-Werror,-Wsometimes-uninitialized]
        if (avail >= 64) {
            ^~~~~~~~~~~
src/fdr/teddy_runtime_common.h:388:27: note: uninitialized use occurs
here
    val = loadu_mask_m512(val, j, ptr);
                          ^~~
src/fdr/teddy_runtime_common.h:359:9: note: remove the 'if' if its
condition is always true
        if (avail >= 64) {
        ^~~~~~~~~~~~~~~~~
src/fdr/teddy_runtime_common.h:351:5: note: variable 'val' is declared
here
    m512 val;
    ^

Always initialize 'val' to zero upon declaration.
