[PATCH] rust: Oe-selftest error log on console when it fails.

[Yash.Shinde@windriver.com]

From: Yash Shinde <Yash.Shinde@windriver.com>

The rust oe-selftest output error log doesn't show any information on console when it fails.
The following changes emit stderr logs in terminal along with re-directing stdout and stderr to "summary.txt" file.

Changes made::
- cmd = cmd + " cd %s; python3 src/bootstrap/bootstrap.py test %s --target %s > summary.txt 2>&1;" % (builddir, testargs, targetsys)
+ cmd = cmd + " cd %s; python3 src/bootstrap/bootstrap.py test %s --target %s  > summary.txt 2> >(tee summary.txt >&2);" % (builddir, testargs, targetsys)

> summary.txt:                  Redirects the standard output (stdout) of the command to a file 'summary.txt'
2> >(tee summary.txt >&2):      Redirects stderr & stdout to summary.txt & writes stderr on terminal

The overall effect is that both stdout and stderr are captured in the summary.txt file, while stderr still being displayed in the terminal.
