Item12671: fix MemoryCycleTests (wouldnt find setlib.cfg otherwise)

Item12671: add $foswikihome/lib/CPAN/lib to FOSWIKI_LIBS when calling build.pl

...otherwise it wouldn't find Class::Load. This should really be put in
@INC automatically, not sure why this is not (no longer?) the case.

Item12671: make sure rootTmpDir does not contain spaces

$this->{project} can apparently be "Foswiki-1.2.0_999 svn-auto17114",
build scripts elsewhere don't expect spaces in directory names (e.g.
when exporting variables on the shell)

[and I'm not sure I like how perltidy made this look...]
