kprobes: Make arch_check_ftrace_location static

arch_check_ftrace_location() was introduced as a weak function in
f7f242ff0044 ("kprobes: introduce weak arch_check_ftrace_location()
helper function") to allow architectures to handle kprobes call site
on their own.

Recently, the only architecture (csky) to implement
arch_check_ftrace_location() was migrated to using the common

As a result, further cleanup the code to drop the weak attribute and
rename the function to remove the architecture specific
