[ Upstream commit 27141b690547da5650a420f26ec369ba142a9ebb ]
The PAC exec_sign_all() test spawns some child processes, creating pipes
to be stdin and stdout for the child. It cleans up most of the file
descriptors that are created as part of this but neglects to clean up the
parent end of the child stdin and stdout. Add the missing close() calls.

[ Upstream commit 96dddb7b9406259baace9a1831e8da155311be6f ]
When checking MTE tags, we print some diagnostic messages when the tests
fail. Some variables uses there are "longs", however we only use "%x"
for the format specifier.
Update the format specifiers to "%lx", to match the variable types they
are supposed to print.

There is a 'malloc' call, which can be unsuccessful.
This patch will add the malloc failure checking
to avoid possible null dereference and give more information
about test fail reasons.
