maint: rely on gnulib's new sys_resource module

* bootstrap.conf (gnulib_modules): Add sys_resource.
* src/sort.c: Remove #if HAVE_SYS_RESOURCE_H guard around inclusion
of <sys/resource.h> and move the inclusion "up" into the alphabetized
list of its peers.  This also avoids a failure of the
sc_prohibit_always_true_header_tests syntax-check rule.
* m4/jm-macros.m4 (gl_CHECK_ALL_HEADERS): Remove sys/resource.h.
