mcexec: workaround for overlayed /sys FS directory lseek() bug
...
lseek() on directories under /sys filesystem that are part of an
overlayed filesystem behave differently than in the original /sys.
This causes segfault in libnuma when discovering topology
information. The patch fakes return value as it is supposed to be,
which also fixes the Intel MPI 2017 MPI_Init() crash.
