Set Makefile SHELL to bash instead of /bin/bash for better portability.

Some systems do not install binaries to /bin, and therefore do not
provide /bin/bash. OS distributions such as NixOS and Guix System
intentionally avoid implementing the Filesystem Hierarchy Standard (FHS).

The recipies inside arch/um/Makefile don't require top-level Bash to
build, and setting "SHELL" to "bash" makes Make pick the Bash executable
from the environment[2], hence this patch.
