Refactor local `execvpe(3)` implementation
The previous code was prone to conflicts with when the platform happens
to expose a `execvpe(3)` implementation in its libc.
This commit renames the internal implementation to `__hsunix_execvpe` as
well as adding an autoconf-detection for the presence of `execvpe(3)`,
in which case `__hsunix_execvpe()` forwards the call to `execvpe(3)`.
Moreover, the code has been cleaned up to remove likely bitrotted CPP
conditionals.
This should fix #22
(This also partially addresses #11 on platforms which have a
libc-provided `execvpe(3)`)
