[LTP] [PATCH] pounder21: Replace {r,}index() with str{r,}chr()

[Alistair Strachan]

The index() and rindex() functions were removed in POSIX.2008. They are
not implemented by Android's bionic C library for 64-bit platforms.

Use the more portable strchr() and strrchr() functions from C89.

Affects fancy_timed_loop, infinite_loop, run-helper, and timed_loop
targets.
