software-dev.cfg will use most recent version of OSIE coupler code.

prevent auto-detection from linking against system libraries when they
are available.

Running theia with yarn start cause PATHs like this to be
added to $PATH

/srv/slapgrid/slappart15/tmp/yarn--1675226243379-0.20314216826775944/node

Similar to debian's default /etc/skel

this can be used to install linters such as pylint when the python
extension prompts for it

also add ~/.local/bin in user $PATH to prevent warning and to be
able to use pip installed packages from the shell.

update all egg versions for python packages used in theia

make zc-buildout.python.executable relative to instance

This settings.json is only generated one, so we can not use the
absolute path, because this will reference an old version of software

This does not work as expected with in this situation :

   bash-5.1$ which slapos
   /usr/bin/slapos
   bash-5.1$ /usr/bin/which slapos
   /opt/slapgrid/d4af5a4bc0958cc5f60fac0dbf6c916e/bin/slapos
   bash-5.1$ ls -al /opt/slapgrid/d4af5a4bc0958cc5f60fac0dbf6c916e/bin/slapos
   -rwxr-x--- 1 slapsoft slapsoft 3492 Jan 31 10:01 /opt/slapgrid/d4af5a4bc0958cc5f60fac0dbf6c916e/bin/slapos
   bash-5.1$ id
   uid=957(slapuser39) gid=1041(slapuser39) groups=1041(slapuser39),1001(slapsoft)

This was downloading pcre2 from git or using system package if available

This is a fixup of 665166e2 (see
especially 665166e2 (comment 177402))

see https://chromium.googlesource.com/chromium/tools/depot_tools.git#updating

as a result, this checkout was not pinned and software was not
reproducible

also make sure component/slapos/buildout.cfg is installable in Theia:
 * we can't compile old gobject-introspection with Python3.9
 * we can't patch dbus as it is read only
