[bug#66525] [PATCH 7/7] gnu: public-inbox: Remove dependency on (guix build syscalls).

[Ludovic Courtès]

* gnu/packages/mail.scm (public-inbox)[arguments]: Remove #:imported-modules.
Remove (guix build syscalls) from #:modules.  Rewrite ‘check’ phase to
reap processes from the build process.
[native-inputs]: Remove TINI.
