eslint: Ignore the meson-* & subprojects folder in the workspace

Modify eslint configuration to ignore the meson-* folder (ignores
the meson build log files - that fails(below) the json validation
test). This helps users to re-use the build directory while running the
local CI.

Also ignoring the meson subprojects folder as , we dont want eslint to be checking
for errors that are not part of openbmc.

Fixes :
