FindBLAS: Extend search directories for MKL
Even though Intel MKL typically puts the libraries under
`$MKLROOT/lib/$arch_$os` some installations may still use
`$MKLROOT/lib/$arch/` path. Ideally, `$arch` should be a
symlink to `$arch_$os`, but sometimes the opposite happens
(for instance, see Intel MKL distribution in Arch Linux [1]),
and sometimes only `$arch` directory alone is present.
This patch extends the search list with `$MKLROOT/lib/$arch` with
lower priority than `$MKLROOT/lib/$arch_$os`, as the latter is the
official path to Intel MKL libraries.
It is also worth mentioning that Intel MKL Link Line Adviser [2]
recommends using `$MKLROOT/lib/$arch` directory in a link line:
```
-L${MKLROOT}/lib/intel64 -Wl,--no-as-needed -lmkl_intel_lp64
-lmkl_sequential -lmkl_core -lpthread -lm -ldl
```
