Make the coverage.config obj exclusion match on Linux

[davidnmbond]

The coverage.config source exclusion for obj was written with Windows-only path separators, so on our Linux CI runners it matched nothing, and source-generated files under obj/ (Refit clients, logging generators) counted towards coverage. Measured before the fix: Meraki.Api's coverage report included 29 such files, PanoramicData.OData.Client's 1.

The pattern is now .*[\\/]obj[\\/].*, which matches either separator, so it works on both the Linux runners and Windows workstations.

Tracked on OPS-157454.

Coverage variation details

	Coverable lines	Covered lines	Coverage
Common ancestor commit (3d65d91)	6192	2018	32.59%
Head commit (216edb9)	6192 (+0)	2018 (+0)	32.59% (+0.00%)

Coverage variation is the difference between the coverage for the head and common ancestor commits of the pull request branch: <coverage of head commit> - <coverage of common ancestor commit>

Diff coverage details

	Coverable lines	Covered lines	Diff coverage
Pull request (#52)	0	0	∅ (not applicable)

Diff coverage is the percentage of lines that are covered by tests out of the coverable lines that the pull request added or modified: <covered lines added or modified>/<coverable lines added or modified> * 100%
