cmake/isal-l: explicitly configure libdir to avoid wrong libisal.a

location.

This is to fix the following libec_isa.si build error :

FAILED: lib/libec_isa.so

-Wl,--dependency-file=src/erasure-code/isa/CMakeFiles/ec_isa.dir/link.d

ninja: build stopped: subcommand failed.

It looks like [under some circumstances?] the building procedure puts
resulting .a under src/isa-l/install/lib64 path which causes lookup
error .so linkage.

This patch enforces lib64 usage.
