tests/defs.in: Quote $srcdir, $PATH; skip libtool and gettext tests.

[Ralf Wildenhues]

This patch finally allows the majority of tests to succeed in a
setup where Automake's absolute source and build tree names contain
white space (assuming all other pending patches are applied).

It makes little sense to run the gettext and libtool tests this way:
the setting of $ACLOCAL which contains the now-absolute $srcdir will
certainly fail.  Also, libtool itself cannot cope with spaces in the
absolute build tree, at least in most cases.

A couple of notes: since defs.in sets `$srcdir' to an absolute value
(before unsetting it), I decided to quote it everywhere in defs.in.

Actually, since most of the remaining test failures are due to
am_aux_dir, they can be worked around with:
  PATH=$PATH:$source_tree/lib
  MISSING=missing
  install_sh=install-sh
  export PATH MISSING install_sh
  make -e check

Cheers,
Ralf
