[Buildroot] [git commit] board/qemu: fix post-image

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=131cb09c79ffe155c51444b5b86145d9e184c304
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Last-minute changes to d9b244d8a3c8 (board/qemu: define start qemu
script outside of post-image script) were not tested before being
pushed, so they introduced a bug.

As Arnout put it:
    [...] multiple expressions need a -e to interpret them as
    expressions (now they're interpreted as file names).

Fixes: d9b244d8a3c83b39f67444f36b21a88cbaf4547b
