[Libguestfs] [PATCH] tests: do not assume '.' is in Perl's @INC

[Pino Toscano]

Upstream Perl is going to remove '.' from @INC (the include path for
modules) by default for the next major release (= 5.26) [1], as measure
to fix security issues.  Debian already started backporting the fixes
for this [2], thus behaving this way in current Sid installations.

Since the affected Perl sources are only the local daemon testing
scripts, a simple fix is to force the 'requires' for the local
captive-daemon.pm module to start from the current directory: this way
there is no need to manually augment @INC, and only our local module is
loaded automatically.
