doc: fix Meson warning about install_subdir

Browse source 
../../git/weston/doc/sphinx/meson.build:97: WARNING:
Project targets '>= 0.63.0' but uses feature deprecated since '0.60.0':
install_subdir with empty directory. It worked by accident and is buggy.
Use install_emptydir instead.

I get the above warning on a clean build, because the directory in
question is empty at configure time. It gets populated at compile time.

Having to exclude one file from the build complicated fixing this.
custom_target() does not support install-excludes, and it looks like
Sphinx does not allow locating the buildfile elsewhere. One option would
be to use a meson.add_install_script() to delete the unwanted file after
it has been installed, but this seemed more complicated than the
solution I chose.

The intermediate build directory name needs to change from 'doc' to
'weston', so that I don't need to strip_directory which custom_target
does not support. The 'output' array in custom_target() also does not
allow outputs to be speficied in sub-directories.

The sh script is tidied up a little bit with set -e, otherwise it would
have become unreadable.
