tests: rename all tests so that their names end in .test suffix

Due to automake limitations, some features work only for tests
that end in one of the suffixes listed in TEST_EXTENSIONS.

* tests/detach-running: Rename to detach-running.test.
* tests/detach-sleeping: Rename to detach-sleeping.test.
* tests/detach-stopped: Rename to detach-stopped.test.
* tests/net: Rename to net.test.
* tests/ptrace_setoptions: Rename to ptrace_setoptions.test.
* tests/qual_syscall: Rename to qual_syscall.test.
* tests/sigaction.sh: Rename to sigaction.test.
* tests/stat: Rename to stat.test.
* tests/strace-f: Rename to strace-f.test.
* tests/Makefile.am (TESTS): Update.
(LOG_COMPILER): Rename to TEST_LOG_COMPILER.
