don't include (ancient version of) Time::HiRes as Perl extension, since it's a core Perl module

[boegel]

This reverts #5616 .

Including Time::HiRes as extension doesn't make sense, since it's a core Perl module (that is, it's always available).

Moreover, the Time::HiRes version that was included in #5616 is an ancient version, or some kind of customised fork of the official Time::HiRes.

Some installations are currently failing because of this:

• BioPerl: "tv_interval" is not exported by the Time::HiRes module
• proovread: "usleep" is not exported by the Time::HiRes module

This change was done for QUAST (cfr. #5610), but QUAST-4.6.0-foss-2016b-Python-3.5.2.eb builds just fine on top of Perl/5.24.0-foss-2016b that doesn't include Time::HiRes as an extension...
