Subject: [PATCH] perf: Remove strchr() in map__process_kallsyms_symbol().

This is looking for '[vdso]', '[vsyscall]' or similar to
force the "kernel" boolean arg to __symbols__insert() to
false.

But such things never show up in kallsyms.

This check was added by commit 608c34de0b3d ("perf symbols: Mark if a
symbol is idle in the library")
