Change libseccomp logic to not be automagic only
Introduce --without-libseccomp configure option so that users can
disable seccomp even if libseccomp is available on the system.
The default is unchanged from before this patch. If no
--with(out)-libseccomp has been given on the command line, the macro
looks for presence of libseccomp and uses that if found.
* m4/man-libseccomp.m4: Guard pkg-config test with a command-line
option.
