[Buildroot] [git commit] genrandconfig: fix the case when outputdir is 'output'

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=1e70470545c348c21f521fa6b7b4cf707d989aad
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When outputdir is 'output' (the default), genrandconfig didn't work
correctly because it expects the configfile in outputdir, while
Buildroot puts it in the buildroot directory.

Fix this by explicitly checking if outputdir == buildrootdir/output.
Because abspath is used for both paths, string comparison works
reliably.
