minijail: refresh lib{syscalls|constants}gen.c for linux-x86 host Crosvm with sandbox on x86 host as of Feb. 28 2020 fails with this error: libminijail[43171]: compile_file: /usr/.../.../block_device.policy(19): nonexistent syscall 'statx' block_device.policy whitelisting statx, where the libsyscalls.gen.c is missing it Likely the two lib*.gen.c files were created a while ago when glibc version was low. Needs refresh. Bug: 150394301 Test: Run cuttlefish enabling crosvm sandboxing with the rebuilt libminijail.so, and saw no error Change-Id: I4f9ebecf1301571d53d127a5cb6eb40b7230b522

Minijail is a sandboxing and containment tool used in Chrome OS and Android. It provides an executable that can be used to launch and sandbox other programs, and a library that can be used by code to sandbox itself.
