File chmod test failing on RTEMS

[jphickey]

Describe the bug
When running unit tests against the latest baseline, there is a new failure on RTEMS:

[BEGIN] 04 TestChmod
OS_FileOpen_Impl():111:open(/RAM/Filename1): Invalid argument
[ FAIL] 04.001 file-api-test.c:257 - status after creat = -1
[ FAIL] 04.002 file-api-test.c:259 - status after close = -16

To Reproduce
Build with unit tests and execute on RTEMS 4.11 + pc686 + QEMU as documented in README. The chmod test fails.

Expected behavior
Test should pass.

System observed on:
RTEMS 4.11.3, pc686 BSP, running in QEMU

Additional context
Appears to be introduced in PR #665

Reinforces need (again) for CI script that runs the RTEMS build.

I took a quick look, I think the issue is related to the way the test file is initally created:

osal/src/tests/file-api-test/file-api-test.c

Line 256 in 9407cdf

status = OS_OpenCreate(&fd, filename, OS_FILE_FLAG_CREATE | OS_FILE_FLAG_TRUNCATE, OS_READ_ONLY);

It doesn't make sense to use OS_FILE_FLAG_CREATE | OS_FILE_FLAG_TRUNCATE in combination with OS_READ_ONLY ... I believe the OS is probably catching this as invalid.

Also dug into it and the FileOpen_Impl has a comment saying the same thing about read only. I can change the test to start with Read Write instead if you think that will fix the problem.

What's the status here? Can we get a fix in this round?
