Message:

Runtime/linux/sysfs.cpp: Fixes for the tstRTSystemQueryDmi testcase, don't seek to the end of the file to get the file size because that is often bogus for sysfs entries (the indicated file size is much bigger than what can be read really). Fix an inconsistency in RTLinuxSysFsReadStrFileV() which would return a VERR_BUFFER_OVERFLOW error if the given buffer matches the string size if there is a newline end the end which is filtered out anyway. Small adjustment for RTLinuxSysFsWriteStr() to also write zero terminators if the string size is not given
