lib/pager: minor compiler warning fixes

Add missing function prototype, and declare structure before use of it.

lib/pager.c:162:6: warning: no previous prototype for function 'setup_pager' [-Wmissing-prototypes]
lib/pager.c:20:29: warning: tentative definition of variable with internal linkage has incomplete non-array type 'struct child_process' [-Wtentative-definition-incomplete-type]
