um: Add definition of __NR_close_range for older host OSs
PATCH 1/1 um: Add definition of __NR_close_range for older host OSs
__NR_close_range was introduced with 278a5fbaed89dacd04e9d052f4594ffd0e0585de ("open: add close_range()") which is present in Linux >= 5.9. Older hosts running a kernel version prior to that range currently fail to build due to that missing system call number definition.
Fixes f82a9e7b9fa9 ("um: fix execve stub execution on old host OSs")
