testing/ostest: add strto base tests
Add regression coverage for integer conversions with explicit bases from 2
through 36. Exercise lower- and upper-case digits, positional values, all six
strto* interfaces, end pointers, errno, and the invalid range boundaries.
The tests fail at base 27 without apache/nuttx#19594 and pass with the
corresponding libc fix.
