ceamac f88b4c08e7 Handle SIGINT/SIGTERM in run_process_foreground for -r

Previously, Ctrl-C or `kill` during -r's bwrap run left slocker_lite
killed outright (default signal disposition), skipping
run_container()'s unmount/cleanup entirely and leaving the layer
imported and/or mounted as garbage.

run_process_foreground() now installs a handler around its waitpid()
that forwards the signal to the running child (kill(), async-signal-
safe) and keeps waiting (EINTR-retry loop) instead of dying. Once the
child actually exits, control returns normally so the existing
unmount/cleanup runs as usual.

Verified with a backgrounded `-r ... -- /bin/sleep 30`, sending both
SIGINT and SIGTERM to the outer slocker_lite PID: process tree exits
cleanly, unmount+delete-layer both run, containers-storage layers
returns to baseline.
