[GIT PULL] RTLA: Fixes for 7.2

[Steven Rostedt]

Linus,

RTLA fixes for v7.2:

- Fix missing unistd include

  A missing #include <unistd.h> broke build on uclibc systems.
  Add the include to fix it.

- Fix missing tools/lib/ctype.c dependency

  RTLA links tools/lib/string.c as a dependency of libsubcmd, some of its
  functions require _ctype. Link tools/lib/ctype.c as well, to fix build
  without GCC LTO.

[GIT PULL] rtla: Fixes for 7.2

[Steven Rostedt]

Linus,

rtla fixes for 7.2:

- Fix and cleanup .gitignore

- Fix pgrep filter in get_workload_pids.sh

  Fix parsing of kernel thread names in get_workload_pids() helper
  function. On some systems pgrep matches kernel thread names including
  the brackets (e.g. "[osnoise/0]") and other systems brackets are not
  included. Fix the tests to handle both.
