While here, fix a bug in which NANO_PMAKE would not be appended at the
appropriate time.
Simply move both checks to after the call to set_defaults_and_export().

Some users build FreeBSD as non-root in Perforce workspaces. By default,
Perforce sets files read-only unless they're explicitly being edited.
As a result, the -f argument must be used to cp in order to override the
read-only flag when copying source files to object directories. Bare use of
'cp' should be avoided in the future.
Update all current users of 'cp' in the src tree.

contains the libraries for Address Sanitizer (asan), Undefined Behavior
Sanitizer (ubsan) and Profile Guided Optimization.
ASan is a fast memory error detector. It can detect the following types
of bugs:
Out-of-bounds accesses to heap, stack and globals
Use-after-free
Use-after-return (to some extent)
Double-free, invalid free
Memory leaks (experimental)
Typical slowdown introduced by AddressSanitizer is 2x.
UBSan is a fast and compatible undefined behavior checker. It enables a
number of undefined behavior checks that have small runtime cost and no
impact on address space layout or ABI.
PLEASE NOTE: the sanitizers still have some rough edges on FreeBSD,
particularly on i386. These will hopefully be smoothed out in the
coming time.

The work in r258233 hardcoded the assumption that tests was the last component
of the tests tree by pushing tests as an explicit prefix for the paths in
BSD.tests.dist and /usr was the prefix for all tests, per BSD.usr.dist and all
of the mtree calls used in Makefile.inc1. This assumption breaks if/when one
provides a custom TESTSBASE "prefix", e.g. TESTSBASE=/mytests .
One thing that r258233 did properly though was remove "/usr/tests" creation
from BSD.usr.dist -- that should have not been there in the first place. That
was an "oops" on my part for the work that was originally committed in r241823

Summary:
This change converts NanoBSD into a two-script bundle.
- defaults.sh contains all non-CLI code. Most NanoBSD code is moved into
this file.
- nanobsd.sh now consists just of a command line interface that calls into
functions in defaults.sh.
Test Plan: Run NanoBSD using a previously-working configuration.
