[PATCH v2 2/5] rtems-exeinfo.cpp: Restore ostream format

[Ryan Long]

CID 1503006: Not restoring ostream format
CID 1503007: Not restoring ostream format

Used a variable to store the format of the ostream before any changes,
and copied what was originally there back into the stream before
returning from the function.

Closes #4469
