t0001: skip test with restrictive permissions if getpwd(3) respects them

Browse Source 
The sub-test "init in long base path" in t0001 checks the ability to
handle long base paths with restrictive permissions (--x).  On OpenBSD
getcwd(3) fails in that case even for short paths.  Check the two
aspects separately by trying to use a long base path both with and
without execute-only permissions.  Only attempt the former if we know
that getcwd(3) doesn't care.
