[PATCH] perf build: Fix static build of dlfilters

[Leo Yan]

Commit e1065ed188cf ("perf build: Add LDFLAGS to dlfilters .so link")
passes LDFLAGS when linking dlfilter shared objects. That breaks static
builds because LDFLAGS can contain -static, leading to an invalid link
command.

dlfilters are always built as shared objects, even for a static perf
binary. Filter out -static for the dlfilter .so link while preserving
the rest of LDFLAGS.
