valgrind-devel needs update for El Capitan

[barrettsa@…]

Install of valgrind-devel on El Capitan (10.11) fails as follows:

--->  Fetching distfiles for valgrind-devel
Error: valgrind-devel @3.12.0-r15685 is only compatible with Mac OS X versions from 10.5 up to 10.10
Error: org.macports.fetch for port valgrind-devel returned: incompatible Mac OS X version

Modifying the test on line 114 of the port file (and the corresponding version reference on line 115) permits the install to succeed:

    113     pre-fetch {
    114         if {${os.platform} eq "darwin" && (${os.major} < 9 || ${os.major} > 15)} {
    115             ui_error "${subport} @${version} is only compatible with Mac OS X versions from 10.5 up to 10.11"
    116             return -code error "incompatible Mac OS X version"
    117         }
    118     }
