compilers: introduce get_exe() and get_exe_args()

This will be used by rustdoc tests because the Test objects takes a
single string for the command and everything else goes in the args.
But apart from this, the need to split the executable from the
arguments is common so create new methods to do it.

While at it, fix brokenness in the handling of the zig compiler, which
is checking against "zig" but failing to detect e.g. "/usr/bin/zig".
