sci-misc/boinc: New r2 ebuild for boinc-7.4.42 with vsyscall fix

Gentoo-Bug: 577490, 578750

A check against VSYSCALL kernel options was added.
Russell Knighton found out, that some projects segfault if VSYSCALL
mappings are completely disabled, and reported the issue in bug
578750.

The check against CONFIG_LEGACY_VSYSCALL_NONE and
CONFIG_X86_VSYSCALL_EMULATION is based on his patch submitted in the
bug reported by him.
