[Buildroot] [git commit] package/lvm2: disable parallel build

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=bedd8420786b184f4aec4433800083a3468cfe1c
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Parallel build is broken since bump to version 2.03.12 in commit
80997acd35. Commits 4526078d1b, 8a313b019c, and a7186cd1ea tried to fix
that by only installing systemd units when appropriate.

It turns out that there are more cases where parallel build still fails:

Or:

        [CC] dmsetup

    [...]

Similar traces in either case: it tries to build dmsetup twice, at
intall time instead of build time.

Fixes:
  - http://autobuild.buildroot.org/results/995/995f46ee0033e34261ba7b24b61c41e7a088602b/
  - http://autobuild.buildroot.org/results/a4e/a4ea87da502272dc2e677123b6fbcb0c23106f0b/

Note that this is just a workaround for a broken buildsystem anyway:
indeed, the build of dmsetup is done at install time, instead of build
time. More fixes should be worked on with upstream to properly fix the
issue...
