Added support to show filenames of pinned objects.
For example:
root@test# ./bpftool prog
3: tracepoint name tracepoint__irq tag f677a7dd722299a3
loaded_at Oct 26/11:39 uid 0
xlated 160B not jited memlock 4096B map_ids 4
pinned /sys/fs/bpf/softirq_prog
4: tracepoint name tracepoint__irq tag ea5dc530d00b92b6
loaded_at Oct 26/11:39 uid 0
xlated 392B not jited memlock 4096B map_ids 4,6
root@test# ./bpftool --json --pretty prog

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
