Upgrade ftp/wget from 1.19 to 1.19.1

Changelog: http://git.savannah.gnu.org/cgit/wget.git/plain/NEWS

• add test target and TEST_DEPENDS
• remove gmake from USES: current version of wget can be build without gmake
• unbreak IDN option: since 1.19 wget uses libidn2 instead of libidn
• libidn2 uses libunistring from ports, so when the IDN option is enabled use libunistring from the ports instead of the bundled one
• disabling pcre support using ./configure --disable-pcre currently works, use it
• remove Makefile and configure patches which are no longer needed
• patch /usr/local to $PREFIX in wget.info too
• delete files/patch-src__main.c - this bug has been fixed on Mar 2, 2015 [1]
