The statvfs() call depends on the underlying filesystem supporting this. On RTEMS, the IMFS filesystem type does not, and it returns the ENOSYS errno. This is better translated to OS_ERR_NOT_IMPLEMENTED rather than OS_ERROR.

Describe the contribution
Map the ENOSYS errno to OS_ERR_NOT_IMPLEMENTED, which is more appropriate than OS_ERROR.
Fixes #454
Testing performed
Build and execute unit tests on RTEMS 4.11.3
Expected behavior changes
Unit test cases which use OS_statfs and run on an RTEMS IMFS volume (default for the root file system) will be skipped and categorized as "NA" due to OS_ERR_NOT_IMPLEMENTED response, rather than a failure.
System(s) tested on
RTEMS 4.11 on pc686 via QEMU
