Heya,

Another round of patches around the test suite. This time the patches
fix tests that run under LD_PRELOAD=libhostname.so and when cURL is
built with Address Sanitizer (-fsanitize=address).

The first patch ("runtests.pl: simplify command environment handling")
actually contains three changes:
 - Convert from shell commands to an array of arguments.
 - Implement a subset of IPC::Run as AIX does not have this module.
 - Implement a custom subroutine that splits a shell command into an
   array. This is done because Text::ParseWords is broken and does not
   handle some cases correctly.

The second patch further restricts the scope of environment variables.

Reviews / comments are appreciated!

Kind regards,
Peter
