[PATCH v2 13/18] perf vdso: Constify dso parameter in dso__is_vdso()

[Ian Rogers <irogers@google.com>]

dso__can_shrink_symbols(const struct dso *dso) needs to query
dso__is_vdso(dso) on a const struct dso pointer to exclude vDSO images
from symbol shrinking.

Change the parameter of dso__is_vdso() from 'struct dso *' to
'const struct dso *'.
