meta: toolchain-shar-relocate.sh: Do not use $target_sdk_dir as regex

The $target_sdk_dir path might contain special characters, for example if
the path is /opt/poky/3.2+snapshot . Prevent grep from interpreting those
as part of the regex by using the -F parameter and multiple -e parameters
to specify which strings to filter out. Also note that the previous regex
was using asterisk as wildcard (e.g. environment-setup-*), but that should
have been regex (e.g. environment-setup-.*, with dot) to match correctly,
this is also fixed by this change.

Fixes: 9721378688 ("toolchain-shar-template.sh: Make relocation optional.")
