This change updates the perf-utils library to 0.6.0 which has some fixes
for automatically detecting the correct tracefs mountpoint if available.

With `--runtime.gomaxprocs=0`, the GOMAXPROXS value will default to the
number of logical CPUs. In this case, it is more useful to log the
actual value than the value set by the user via the command-line.

NOTE: This changes the Go runtime "GOMAXPROCS" to 1. This is done to limit the
concurrency of the exporter to 1 CPU thread at a time in order to avoid a
race condition problem in the Linux kernel (#2500) and parallel IO issues
on nodes with high numbers of CPUs/CPU threads (#1880).

Avoid running on all CPUs by limiting the Go runtime to one CPU by
default. Avoids having Go routines schedule on every CPU, driving up the
visible run queue length on high CPU count systems.
This also helps workaround a kernel deadlock issue with reading from
sysfs concurrently.

Some systems have broken netlink messages due to patched kernels. Since
these messages can not be parsed, add a flag to fall back to parsing
from `/proc/net/dev`.

Note however that the InetDiagMsg struct contains a InetDiagSockID
member, which itself contains some members which are explicitly
specified as big-endian in Linux kernel source:
struct inet_diag_sockid {
__be16 idiag_sport;
__be16 idiag_dport;
__be32 idiag_src[4];
__be32 idiag_dst[4];
__u32 idiag_if;
__u32 idiag_cookie[2];
};
node_exporter currently does not use these members for anything, so this
is acceptable (for now).

The textfile collector will now provide a unified metric description
(that will look like "Metric read from file/a.prom, file/b.prom")
for metrics collected accross several text-files that don't already
have a description.
Also change the error handling in the textfile collector tests to
ContinueOnError to better mirror the real-life use-case.
