selinux: fix BPF token permission checks

Avoid multiple lookups of the bpffs creator SID using the token's file
descriptor when the same information can be found via the resolved
path/dentry (in selinux_bpf_token_create()) or the token itself (in
selinux_bpf_map_create() and selinux_bpf_prog_load()). Not only does
this simplify the code, it avoids potential TOCTOU issues if the user
changes the token file descriptor passed into the kernel.
