From: Björn Töpel <bjorn@rivosinc.com>

Currently, "make install" does not install the required test_progs
"extra files" (e.g. kernel modules, helper shell scripts, etc.) for
the BPF machine flavors (e.g. cpuv4).

Add the missing "extra files" dependencies to rsync, called from the
install target.

Unfortunately, kselftest does not use bash as the default shell, so
the globbering is limited. Blindly enabling "SHELL:=/bin/bash" for the
Makefile breaks in other places. Workaround by explicitly call
"/bin/bash" to expand the file globbing.

v3: Do not use hardcoded file names (Andrii)
v2: Added btf_dump_test_case files
