kbuild: parameterize the .o part of suffix-search

Browse Source 
The suffix-search macro hard-codes the suffix, '.o'.

Make it a parameter so that the multi-search and real-search macros
can be reused for foo-dtbs syntax introduced by commit 15d16d6dad
("kbuild: Add generic rule to apply fdtoverlay").
