Subject: [RFC PATCH 1/5] perf trace: Apply config options in '.perfconfig'

'perf trace' doesn't read and apply options in ~/.perfconfig. If a BPF
script is passed to 'perf trace --ev' and clang is not in $PATH,
perf trace doesn't compile the script even clang-path is configured in
~/.perfconfig.

This patch makes 'perf trace' read and apply default config options
from that file.
