[BUG] watchexec2 breaks build on termux and will soon stop compiling

[dead10ck]

Environment

• OS: Termux on Android 12
• Dotter version: 61ebe010f1ec073b3db4520dd26b843f6ead4b71 and later

Description

61ebe010f1ec073b3db4520dd26b843f6ead4b71 introduced a new transitive dependency on pwd, which does not build on Android due to getpwent and friends being unavailable in bionic.

Additionally current version of watchexec pulls in dependencies that will stop compiling soon. Should update to latest release, however there are breaking changes.
