devfs: explicitly mount /dev/shm with mode=1777

Browse Source 
The current code relies on the tmpfs mount defaulting to 1777
permissions.  If it doesn't, things break badly.

This can come up when tmpfs is disabled in the kernel and ramfs
is being used instead (the kernel will alias tmpfs to ramfs).
The default permissions for ramfs is 0755.
