KVM: selftests: Add basic selftest for guest_memfd()
Add a selftest to verify the basic functionality of guest_memfd():
+ file descriptor created with the guest_memfd() ioctl does not allow
read/write/mmap operations
+ file size and block size as returned from fstat are as expected
+ fallocate on the fd checks that offset/length on
fallocate(FALLOC_FL_PUNCH_HOLE) should be page aligned
+ invalid inputs (misaligned size, invalid flags) are rejected
+ file size and inode are unique (the innocuous-sounding
anon_inode_getfile() backs all files with a single inode...)
