mapserv: exit FastCGI loop promptly on SIGTERM/SIGUSR1 (#7506)

When mapserv is built with FastCGI and is idle inside FCGI_Accept(),
SIGTERM only sets finish_process=1 and is masked by the SA_RESTART
default of signal(), so the blocking accept()/select() resumes and the
process appears hung until the next request arrives.

Call FCGX_ShutdownPending() from the handler (signal-safe; sets
libfcgi's internal shutdown flag) and install handlers via sigaction()
with sa_flags=0 so the syscall returns EINTR. libfcgi then returns -1
from FCGI_Accept() and the loop exits cleanly.
