nixos-install: clear executable cache after entering chroot

xaverdh · xaverdh · commit 5d470b88351c · 2024-11-11T21:36:45.000+01:00
Clear the cache for executable locations after entering the chroot. The cached locations are no longer valid there. This resolves problems with nixos-install failing to find binaries from coreutils as witnessed in #241356.
