[Buildroot] [git commit branch/2019.02.x] support/testing/infra/emulator: increase memory size used by Qemu

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=a9416689465dfd61e946ba0ee0779cb47dfaca6c
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.02.x

By default, Qemu emulates a system with 128 MB of RAM. This is not
sufficient for some test cases we have, such as TestPerlDBDmysql,
where the initramfs is quite large. Therefore, this commit extends the
RAM size emulated by Qemu to 256 MB.

Fixes:

Thanks to Arnout for the analysis of the issue.
