Subject: [PATCH 1/2] versions: fix --executables portability regression

Replace the use of `xargs -r` and `basename -a` in the
`--executables` fast path with Bash 3.2-compatible parameter
expansion.

The previous implementation relied on non-portable utility options,
causing `pyenv rehash` and shell initialization to fail on illumos,
OpenBSD, and other non-GNU userlands.

Preserve the optimized executable discovery path by continuing to
discover executables directly from the versions directory and
deduplicate their basenames.

Subject: [PATCH 2/2] versions: fix portability regression in --executables

Commit 8037f226 introduced the `--executables` fast path using
`xargs -r` and `basename -a`. Those options are unavailable on
illumos and OpenBSD, breaking `pyenv rehash` on those platforms.

Replace the GNU-specific invocation with a Bash 3.2-compatible
implementation while preserving the direct executable discovery
optimization.
