mds: respawn using /proc/self/exe

This allows the MDS to respawn using the same executable file even if it
has since been deleted (on Linux). Otherwise, the execv fails because
the readlink returns "/path/to/deleted (deleted)". (There is no path to
the old executable.)

(cherry picked from commit 66a122025f6cf023cf7b2f3d8fbe4964fb7568a7)
