Subject: [PATCH 1/2] xbps-src: use internal config in foreign environment

When xbps-install is called without "-C", xbps-install will pick
configuration from the location configured at build time.

Should the default location not have a valid repository configuration,
we couldn't run binary-bootstrap.

Run xbps-install with our internal configuration instead.

Subject: [PATCH 2/2] xbps-src: environment: keep LD_LIBRARY_PATH outside of
 chroot

Using self-built xbps in non-standard location requires setting
LD_LIBRARY_PATH.  Thus, bootstrapping from foreign distribution
with those binaries failed.
