1) added scripts/shell.req.files and scripts/shell.prov.files. scripts/shell.req.files has new patterns for '/usr/bin/env bash' and '/bin/ash'. 2) adapted scripts/shell.req.in and scripts/shell.prov.in by using ArgvFileAction. Also made them work with empty RPM_BUILD_ROOT. Note: now shell.req produces dependencies from .provides.sh even if the latter is inside RPM_BUILD_ROOT. The reason is that .provides.sh and the script can reside in two different subpackages (and otherwise, rpm will optimize out the dependency). 3) removed corresponding old code from autodeps/linux.req.in and autodeps/linux.prov.in.
