From: Pratyush Mallick <[email protected]>

The current .gitignore hardcodes each generated test binary by name,
requiring updates every time a new test is added.

Switch to the patten-matching approach similar to KVM:selftests.
Ignore everything by default and then allow source extensions (.c, .h, .sh)
and tracked non-source files.

Note that un-ignoring *.h files causes the generated local_config.h
build artifact to incorrectly become untracked. A subsequent patch
will rename this header to resolve the issue.
