bootstrap: fix handling of various perl --version formats
* build-aux/bootstrap (get_version): Don't use perl's $] special
variable, as that requires updating all bootstrap.conf files to
use perl's x.yyyzzz version format. Instead make the regular
expression more general to support version formats from older
perl-5.005_002 (5.5.2) and perl-5.11 which has other numbers
in the version line.
