[PATCH 04/20] selftests: add install target to enable installing selftests

[Shuah Khan]

Add a new make target to enable installing selftests. This
new target will call install targets for the tests that are
specified in INSTALL_TARGETS. During install, a script is
generated to run tests that are installed. This script will
be installed in the selftest install directory. Individual
test Makefiles are changed to add to the script. This will
allow new tests to add install and run test commands to the
generated kselftest script.

Approach:

make kselftest_target:
-- exports kselftest INSTALL_KSFT_PATH
   default $(INSTALL_MOD_PATH)/lib/kselftest/$(KERNELRELEASE)
-- exports path for ksefltest.sh
-- runs selftests make install target:

selftests make install target
-- creates kselftest.sh script in install install dir
-- runs install targets for all INSTALL_TARGETS

Individual test make install targets:
-- install test programs and/or scripts in install dir
-- append to the ksefltest.sh file to add commands to run test
