lib/tests: add pathSimplifyTest, covering path canonicalization

Covers eatSlashSlashInPath and eatExcessDotsInPath, which had no test.

The test has two halves. The first prints the canonical form of 41 named
paths and the makefile diffs that against expected/, so a change in behavior
shows up as a diff. Those paths include the cases from #37263: a ".." that
climbs out of a relative path, a "." next to a "..", and a ".." at the root
of an absolute path.

The second half enumerates every path over the alphabets "/.a" up to length 9
and "/.ab" up to length 7, 51369 in all, and compares the answer against a
reference written inside the test. The reference builds a stack of components
instead of walking one buffer with two pointers, so the two are unlikely to
share a mistake. Only the count and the number of disagreements go in the
expected file, which keeps it small while the check stays broad.

A test that cannot fail is worth nothing, so this was checked against the
version of osunix.c from before the fix: it reports 32 differing named lines
and 1949 disagreements with the reference there, and none against the current
code.
