[PATCH 5.4 077/102] selftests: gen_kselftest_tar.sh: Do not clobber kselftest/

From: Kees Cook <keescook@chromium.org>

[ Upstream commit ea1bf0bb18c0bd627d7b551196453ff2fff44225 ]

The default installation location for gen_kselftest_tar.sh was still
"kselftest/" which collides with the existing directory. Instead, this
moves the installation target into "kselftest_install/kselftest/" and
adjusts the tar creation accordingly. This also adjusts indentation and
logic to be consistent.

Fixes: 42d46e57ec97 ("selftests: Extract single-test shell logic from lib.mk")
