package/hiredis: fix install step for static build only

The previous patch [1] didn't take into acount the static build only
scenario. It tries to unconditionally install a shared library.

Handle the install step like for bzip2 package: install the shared
library only if BR2_SHARED_LIBS or BR2_SHARED_STATIC_LIBS is set and
install the static library only if BR2_STATIC_LIBS or
BR2_SHARED_STATIC_LIBS is set.
