Add comprehensive tests for nohup's file descriptor replacement logic and error handling, increasing coverage of previously untested code paths. New tests cover: - Creating nohup.out in current directory - Appending to existing nohup.out - Stderr redirection to stdout - Command not found error (exit codes 126/127) - Fallback to $HOME/nohup.out when cwd is not writable (Linux/FreeBSD) - POSIXLY_CORRECT environment variable handling (Linux/FreeBSD) Tests use .terminal_simulation(true) to properly test TTY-dependent behavior. Platform-specific tests are gated behind appropriate cfg attributes. Addresses uutils#1857

Working on issue #1857 about nohup test coverage.
What's here:
The uncovered lines:
Line 119 (and similar at L110, L124) are
dup2()syscall error paths. These only trigger if the kernel fails to duplicate file descriptors - basically unreachable without fault injection tools. I documented this in the coverage analysis.The remaining uncovered lines are defensive error handling that's realistically untestable in the current test environment. IMO they should stay as-is - better to have defensive code than risk removing safety checks.
