[Buildroot] [git commit branch/next] nmap: remove redundant --static flag to pkg-config

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=c38869b41b7b6b0ace06884ff13c5d751023b861
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

The pkg-config tool is automatically passing --static when BR2_STATIC_LIBS
is set (see package/pkgconf/pkgconf.mk), so no need to pass it explicitly
from package .mk files.

Additionally, replace a missed occurrence of $(shell) with backticks.
